SMOV 4 Plan Overview … 1 SMOV 4 Plan – Provides for the timely commissioning of the Observatory for science following SM 4 • Commissions the newly SIs on channel-by-channel basis – Introduces GO science on a channel-by-channel basis as SMOV progresses • Recommissions the restored SIs on channel-by-channel basis • Recommissions serviced Observatory Systems • Performs Early Release Observations (EROs) – Satisfies the SMOV 4 requirements of 21 March 2007 3/18/2018 • Plan presented, reviewed, and approved 12 Oct. 2007 (SMR-4029, CCR 5248) 4
Generic SMOV Process following each HST Servicing Spacecraft Subsystems Commissioning Early Release Observations New/Revived Instruments PCS/EPS/TCS… HST Release from Shuttle Focus/Alignment of SI Optics SMOV Start Instrument Preps Engineering Check-Outs Outgassing Cooldown 3/18/2018 Instruments Science Calibrations GO Science Ramp-up As Instruments/Channels Are commissioned 5
SMOVs 2 – 4 EXTERNAL ORBITS HISTORICAL COMPARISON Notes: 1. STIS and NICMOS required more orbits than planned because of the NICMOS thermal short and the opto-coupler resets in both SIs. 2. SMOV 4 seems to be the most complex in terms of realtime interactions and in 3/18/2018 -line analyses. 6
SMOV 4 Plan Overview … 2 SMOV 4 Plan satisfies the following drivers • Perform EROs in time for Jan. AAS release – i. e. , schedule observations in early December 2008 • Minimize excess FGS 3 usage by timely commissioning of FGS 2 R 2 3/18/2018 7
SMOV 4 Plan Overview … 3 SMOV 4 Plan satisfies the following constraints Long intervals for outgassing and contaminants dissipation – Bright Earth Avoidance (for 21 days from Release) • to avoid UV-induced polymerization of exposed optics (WFC 3 POM) – COS NUV = 10 days from Release (per model) to allow internal pressure below 20 u. TORR, before detector activation – COS FUV = 15 days from Release (per model) to allow internal pressure below 10 u. TORR, before detector activation – WFC 3 = 21 days from Release before cal lamp usage and TEC cooldown Careful, incremental initial high-voltage ramp-ups – COS NUV/FUV – STIS NUV/FUV – ACS SBC 3/18/2018 8
SMOV 4 Plan Overview … 4 SMOV 4 Plan prioritizes SMOV activities to allow schedule flexibility Prioritization (High, Medium, Low) – Based on realistic assumptions about scheduling rates (external orbits) – Accommodates ERO schedule and other key dates – Accommodates non-SMOV (eg. , GO, ERS) programs before SMOV completion 3/18/2018 9
Prioritization of SMOV activities • High Priority = activities needed to enable EROs in early Dec. • Medium Priority = activities needed for enabling GO science • Low Priority = all other activities – Needed to satisfy all other SMOV 4 requirements and reference file generation – Needed for handbook inputs in spring 3/18/2018 10
SMOV Prioritization: COS High Priority Activities (EROs) – Through NUV and FUV Alignment and Focus Medium Priority Activities (Science enable) – All FUV cals beyond alignment/focus and target acq test – The rest of NUV wavelength scale calibration Low Priority Activities – Low 1 – needed for reference files and handbook inputs (data needed by Feb. 1) – Low 2 – desirable but not required for handbook inputs – Low 3 – All others 3/18/2018 11
SMOV Prioritization: WFC 3 High Priority Activities (EROs) – Through UVIS & IR Fine Alignment – In parallel with EROs • UVIS/IR/FGS alignment, UVIS/IR plate scales Medium Priority Activities (for “Easy” GO science) – Internal flats, flat-field uniformity, photometric zeropoints Low Priority Activities (for “Hard” GO science) – UVIS/IR image quality, PSF wings, UVIS PSF Core Modulation (shutter test), pointing stability, IR 3/18/2018 12 grisms
SMOV Prioritization: ACS High Priority Activities (EROs) – WFC Optimization Campaign (OC), image quality, sensitivity – SBC turn-on, UV monitor Medium Priority Activities (GO science) – SBC PSF – HRC image quality, sensitivity, geometric distortion, coronagraph commissioning Low Priority Activities – None remaining, but assume the option to delay HRC commissioning in favor of WFC/SBC in early 3/18/2018 SMOV 13
SMOV Prioritization: STIS & NICMOS – High Priority Activities (EROs) • Through Aperture Location activity – Medium Priority Activities (GO science) • Through Aperture Location activity and SIAF update • Aperture knowledge without SIAF may be sufficient STIS – High = STIS External Focus Check – Medium = NUV Optical Format Verification, FUV Image Quality – Low = CCD Spectroscopic Throughput, Image/Pointing Stability, NUV Image Quality 3/18/2018 14

Proposal Processing Status Cycle 17 General Observer Pool 197 GO proposals including those from HST Cycle 17 TAC, Chandra TAC, and previous HST TACs, for 3627 orbits. 16 SNAP proposals, for 1417 orbits. 24 GTO/COS proposals for 291 orbits. 3 GTO/ACS proposals for 24 orbits. 2 ERS proposals for 214 orbits. 3 GO/PAR proposals for 410 orbits. 3/18/2018 27
Proposal Processing Status Cycle 17 General Observer Pool (continued) v v Program Coordinators (PCs) are processing observations in the general pool: ~ 6000 orbits. Instrument teams have begun reviewing these observations and will have most done before SM 4. Remaining will be done according to Long Range Plan schedule. Currently 9% unschedulable, mostly due to incompatibility of requested scheduling constraints (orients, guide stars, timing links, etc. ). This is typical for early ingest; PCs will resolve these issues throughout the coming months. Final processing steps will wait until after SM 4, when the ground system is reconfigured for 3 gyro mode. 3/18/2018 28
Proposal Processing Status After SM 4 v v SMOV proposals and science proposals will be reworked as needed during SMOV. Remaining Cycle 15 and Cycle 16 proposals will be reworked for 3 -gyro scheduling. Cycle 17 pool will continue processing as usual, to execute observations according to the Long Range Plan. Begin processing Cycle 17 calibration proposals (Calibration review on 9/25/08; Phase II deadline TBD). 3/18/2018 29
The Long Range Plan David Adler Science & Mission Scheduling Branch - OED 3/18/2018 30
Long Range Planning Group (LRPG) Activity Summary • Remainder of Cycle 16: – 173 orbits before SM 4, 441 orbits after SM 4 in Cycle 16 “tail. ” • The LRPG is monitoring remaining Cycle 16 WFPC 2 observations. – all but one 3 -orbit To. O follow-up should be completed by SM 4. – PI of that program will put in a request to change SI if needed. • The LRPG has incorporated SMOV, SI commissioning, ERO, ERS, and GTO constraints into the Cycle 17 planning process. • A preliminary Cycle 17 LRP has been built and verified. • The LRPG has identified/developed plans for managing SM 4 contingencies in Cycle 17 planning. 3/18/2018 31
Preliminary Cycle 17 Plan Highlights • December/January priorities: – – – High priority SMOV EROs ERS/GTOs Time-critical Cycle 17 science Medium/low priority SMOV Cycle 16 GO science • Cycle 16 planning information for Oct-Dec programs is being maintained in case of launch slip. • All cycle 16 science planned for Oct-Dec can be replanned for 2009. • Under-subscription in early 2009 – LRPG is leaving space for Cycle 17 calibration programs, Target of Opportunity programs, DD, HOPR repeats, etc. 3/18/2018 32
Preliminary Cycle 17 LRP – Oct-Feb launch BEA SM 4 SI commissioning milestones ACS SBC STIS COS NUV ACS WFC/HRC NIC WFC 3 UVIS “easy” WFC 3 UVIS/IR “hard” COS FUV WFC 3 IR “easy”
LRPG Transition from SMOV to Cycle 17 Science • Preliminary Cycle 17 plan is built • Statistics: 4200 orbits – Cycle 16 and 17 science in working LRP +600 orbits - SMOV/ERO (not in plan) +850 orbits - “unplanned” – 2 orbits a day of calibration, HOPR, To. O, etc -------5650 orbits in Cycle 17 -650 orbits - cycle 17 tail – beyond Dec 31, 2009 =5000 orbits from 10/20/08 – 12/31/09 = 11. 42 orbits/day = 80 orb/week • Plan will not be released to the public until a couple of weeks after deployment when the state of the observatory is known. 3/18/2018 34
LRPG Contingency Plans If there’s a launch slip: • Long Range Plan will be rebuilt to reflect the change. • For a 1 - 4 week slip, the following can fill the gap: – – • Existing Cycle 16 science programs Cycle 17 NIC science that can schedule in 2 -Gyro Cycle 15/16 Snaps Cycle 17 NIC Snaps that can schedule in 2 -Gyro 5 + week slip: – Existing science and Snaps, as described above; studies are ongoing to see how far out this can be extended. – If more science is needed, LRPG will consult with the Science Policies Group (SPG) for a course of action. 3/18/2018 35
Summary - LRPG Readiness for SM 4 • Transition plan between Cycle 16 – SM 4 – SMOV – Cycle 17 is in place. • Preliminary Cycle 17 LRP has been built and is ready for execution. It is currently on-hold pending the outcome of SM 4. • The LRP incorporates all constraints/HST orbit resource requirements of all SMOV (including SI commissioning) and ERO/ERS activities. • Process/policies are in place for updating the Cycle 17 plan in response to SM 4 contingencies. • The LRPG is ready for SM 4! 3/18/2018 36
Contingency plan if STIS and/or ACS are not available • The C 17 TAC recommended programs based on the assumption that SM 4 would be fully successful, i. e. , both STIS and ACS would be repaired • STIS and ACS are scheduled for repair after COS and WFC 3 and their repair is more challenging • Therefore STIS and ACS carry a higher risk of not being available in C 17 than COS and WFC 3 3/18/2018 37
Instrument Contingencies Neill Reid Science Mission Office 3/18/2018 38
C 17 allocation by orbit: • STIS: 8% of total; includes imaging and spectroscopy • ACS: 25% of total; includes 1% of SBC use (currently operational) • Numbers include parallels but no snapshots (1357 snapshot targets awarded in C 17; STIS: 140; ACS: 518) 3/18/2018 39
C 17 proposers were required to address whether their programs could be switched to a different instrument if STIS/ACS were not available Using this information, the TAC endorsed or rejected an instrument switch and made a recommendation to the Director 3/18/2018 40
STIS • Moderate-resolution UV spectroscopy can often be switched to COS • Imaging can almost always be done with WFC 3 or ACS • Optical spectroscopy, spatially resolved spectroscopy, high-resolution spectroscopy, etc. , need STIS • ~40% of all orbits using STIS can be switched • The Long Range Planning Group has run simulations showing that when STIS observations are removed, science with other SIs can be front-loaded in the Cycle 17 long range plan 3/18/2018 41
ACS • Standard broad- and narrow-band imaging can be switched to WFC 3 in most cases • SBC observations continue to be available • Optical coronagraphy, polarimetry, high-resolution imaging, etc. , need ACS • ~85% of all orbits using ACS can be switched • The Long Range Planning Group has run simulations showing that when ACS observations are removed, science with other SIs can be front-loaded in the Cycle 17 long range plan 3/18/2018 42
Impact if STIS/ACS are not available • Using the TAC recommendation as a guide-line and after additional STSc. I review, PI’s will be notified whether instruments can be switched • Process similar to that used when ACS failed and observations were switched to WFPC 2/NICMOS • PIs may appeal to the TTRB if switch was rejected • Switch can be done quickly (1 – 2 months) • Scheduling impact: ≤ 10% of the total orbits (sum of all C 17 orbits) will be lost because the science requirements preclude an instrument switch • Orbits can be replaced, e. g. , by snapshots 3/18/2018 43

Database SMOV Preparation Environment SMOV 4 development utilizes the same methodology that was successfully used for all previous Servicing Missions. Use a separate database and disk space from Operations, but the same machines/servers. – spss_sm 4 database for SMOV 4 development – spss database for current SPSS Operations Uses the operational software and tools, but utilizes different PRD/SCIOPSDB and SMS Instructions – Allows simultaneous Flight Operations and SMOV development – Two environments are isolated The spss_sm 4 database is managed in the same way as the SPSS Operations database. This SMOV 4 environment is used to: – – 3/18/2018 Prepare the SMOV proposals for execution Create the SMGT products Create the SMOV 4 representative products Post-SM 4 DRM Planning and Scheduling exercise 49
Database The Merge Process SMOV environment gets merged into the Operations environment after rendezvous and berthing occurs. Unload all the SMOV 4 and housekeeping proposals from the spss_sm 4 database – This stores the proposals on disk as an sql load file – This part of the process nominally occurs right around launch time and takes about a day Get a backup of the spss database – This allows us to easily restore to pre-launch if necessary Database Administrator moves the contents of specified tables from the spss_sm 4 database into the spss database – This transfers the PRD/SCIOPSDB information and the Instructions needed post-SM 4 Load the SMOV 4 and housekeeping proposals into the spss database Database Administrator will rebuild the table indices to ensure good database performance 3/18/2018 50
Database The Merge Process (cont) Modify any spss database resident housekeeping visits to 3 -Gyro/OBAD mode PRD/SCIOPSDB group will audit the merged spss database for correctness OPS will audit the proposals for correctness End-to-end process generally takes about 2 days. This Merge process will be tested on September 15 th. 3/18/2018 51

Planning and Scheduling Procedures The Procedures are written, configured descriptions of a particular process workflow that describes the tools and actions that should be performed to accomplish that particular workflow. Procedures that need modification to support post-SM 4 – None of these updated procedures will be put into place until after the database merge is complete. • 3. 2. 01 - Scheduling Unit Selection – Remove the WFPC 2 decon references and add in the WFC 3/ACS/STIS Anneal proposals • 3. 2. 02 - Flight Calendar Preparation – Add the STIS Low Voltage management (STISLs) back in • 3. 2. 03 - Flight Calendar Building – Remove the special checks for non-functional ACS/STIS detectors – The following procedures were modified and installed • 3. 2. 17 - Science Instrument Safe Mode Recovery – Add WFC 3/COS and post_SM 4 ACS – All Visits (excepting WFC 3 Soft-Safing) are ready for use 3/18/2018 54
Planning and Scheduling Tools The tools are configured programs or scripts that are used to perform certain actions called out in the Procedures used for building the weekly flight calendars. Tools which have already been modified and being used for the initial SMOV calendar builds – ccl_gsselect • Selects the guidestars used in the SMS • Don’t allow FGS 2 R 2 to be used as the dominant guider – su_gaps. sqr • Calendar Visit summary report • Add COS/WFC 3 3/18/2018 55
Planning and Scheduling Tools (cont) Tools requiring modification for SM 4 – data_vol_report. py • Data Volume report for OPUS • Add COS/WFC 3 and remove WFPC 2 – gimme_snaps. py • Builds the lists of what to schedule on a particular week • Change the default for SI/configs to exclude back to nothing – Calendar/SMS checklists • Checks correctness of flight calendars and SMS’s • Changes yet to be determined All of these tools will be put into place operationally after the database merge is complete. 3/18/2018 56
Rendezvous Transitioning HST to Servicing Mission 4 Objective: prepare HST for rendezvous with the Space Shuttle while maximizing the science content of the launch week SMS Methodology: utilize the nominal P&S Intercept capability – A primary science SMS with “transition” visits – A pre-planned intercept SMS with Gyro-4 test and rendezvous attitude maintenance – Post-launch switch from science to intercept Testing: – Previously used for SM 3 B – Tested during the System Readiness 4. 2 (SR 4. 2) SMGT • Intercept loaded and executing but stopped prior to Gyro-4 test and rendezvous attitude maintenance to reduce test duration 3/18/2018 57
Rendezvous Science SMS science 280 Intercept SMS science 3/18/2018 rend att science 287 load breaks rend att G 4 Tests Rend Att Maint = execution path if launch occurs 58
Rendezvous Key Transition Components Transition Visit – Slews HST to rendezvous attitude (varies with launch date/time) – Configures SIs to nominal states in preparation for real-time safing – Provides intercept point and 2 hours of “dead time” to facilitate interception Science SMS – Nominal science SMS – One Transition visit scheduled for each launch window • Provides for launch delays – Nominal product delivery to GSFC Intercept SMS – Same as science SMS up through the Transition visit – Gyro-4 test and attitude maintenance replace science after Transition visit – Products generated and delivered pre-launch (post-science SMS delivery) • TDRS updates withheld until post-launch 3/18/2018 59
Rendezvous What happens on launch day? Science SMS is executing If launch occurs – Intercept the Science SMS • P&S updates TDRS schedule to match the Intercept SMS • FOT uplinks the Intercept loads – No science after start of launch window +7 h • SIs are safed and NSSC-1 “idled” in real-time at 7 h MET via Command Plan If launch is delayed – Science SMS continues uninterrupted • FOT uplinks the next loads from the Science SMS – P&S generates and delivers an Intercept SMS for the next opportunity 3/18/2018 60
Ephemerides Maintain nominal processing and delivery schedule during servicing mission – Prevents gaps in data • reduces manual intervention • less disruptive to PASS processing – Ensures recent data is available in an emergency deploy situation Support fast turnaround processing and delivery post-deploy – The process is fully automated – P&S personnel will be physically at the STSc. I for these critical ephems to deal with any unexpected problems 3/18/2018 61
Deploy SMS Process Firing Up an Improved HST The deploy SMS is a Health & Safety SMS generated using the nominal H&S generation process – 3 -Gyro Onboard Attitude Determination (OBAD) = “T”mode – Built using NSSC-1 FSW 9. 0 – 36 hour duration – BEA compliant initial attitude provided by PCS – Contains no SI commanding • Allows installation of NSSC-1 FSW 9. 0 and COS FSW – Removes support for COSTAR and WFPC 2 – Fixes a COS Lamp startup failure issue • Allows real-time commanding to configure HST for use Tested during the System Readiness 4. 2 (SR 4. 2) SMGT First Science SMS – NSSC-1 cold-start due to FSW install in previous SMS – Begin SMOV activities – Based upon preliminary SMOV template calendar 3/18/2018 62
SMOV 4 Calendar/SMS Builds Construct representative SMOV products assuming a nominal mission and a nominal SMOV Products will cover the first 4 -5 weeks of SMOV – Determines the scheduling feasibility of the SMOV Plan – Finds any inconsistencies between the different SMOV Proposals These products will be widely distributed for review – Ensures we haven’t missed or misinterpreted something Will be the starting point for building the templates the Flight Calendar Builders will use for flight. Templates will be started by ~T-14 days and handed to the Flight Calendar Builder by their nominal T-11 d build start. Currently have the first 3 weeks built which includes the first four post-BEA days. – As expected, this post-BEA area is oversubscribed in the SMOV plan 3/18/2018 63
P&S Team SM 4 Readiness Operations Training No difference in SPSS and PASS process and procedures between pre and post SM 4 operations Therefore, no special training/instruction required to support post SM 4 operations. All team members participated in training sessions to become familiar with COS and WFC 3 characteristics Team also familiarized with any changes in check tools and procedures related to the return to 3 Gyro operating mode Planning and Scheduling utilizing the Post-SM 4 DRM proposals 3/18/2018 64

Data Distribution The calibration software also gets provided to the user as part of STSDAS. 3/18/2018 105
Current Instruments The pipeline calibration software for the legacy instruments has been reviewed to see whether any changes were needed to support SMOV activities. ACS: The ACS pipeline software will require changes to support the new commanded values of the gain. STIS: No changes required for SMOV support. NICMOS: The NICMOS pipeline have been enhanced with deliveries to OPUS 2008. 3 in order to prepare for reprocessing of pre-SM 4 NICMOS data. WFPC 2: All software development has focused on supporting final reprocessing during SMOV, and the version now in place will be sufficient. 3/18/2018 106
WFC 3 CALWF 3 Version 0. 95 was delivered to OPUS Build 2008. 3. – This version of CALWF 3 has been used to successfully process 100% of the relevant ground-test data from Servicing Mission Ground Test (SMGT) through OPUS. It has also been used by the WFC 3 team to process all the Thermal-Vac (TV) test data. • Testing of CALWF 3 carried out by OPUS as part of standard regression testing for operational OPUS builds using SMGT data, and through a separate OPUS TV pipeline to process WFC 3 thermal-vac data as needed by the WFC 3 team. • OPUS regression testing using SMGT data starts with raw telemetry files (POD files) processes them through Generic Conversion, CALWF 3 and ingests the calibrated results in the archive for WFC 3 team review. • OPUS regression testing validates the entire calibration pipeline system from telescope to delivery to the end user, while processing the TV data validates the algorithms used in CALWF 3 for the calibration. – Updates to the non-linearity and bias-level corrections were identified as result of the latest TV data, as well as bugs in CR rejection algorithms. 3/18/2018 107
WFC 3 CALWF 3 has been tested using thermal-vac data and SMGT data. – Thermal-vac data: • Nearly 60, 000 exposures • Every conceivable detector readout mode, including UVIS Extended Pixel Edge Response (EPER) mode for CTE, and UVIS and IR special warm engineering test readout modes which will be used during the SM 4 functional test. – SMGT data: • Regression test suite for OPUS/CALWF 3 and for complete end-to-end test of all WFC 3 front-end and back-end systems. • 30 visits with 99 exposure lines resulting in 172 individual exposures. • Wide range of possible exposure modes (binned, unbinned, 1 -2 -4 amp readout, UVIS and IR subarrays, …) • 22 associations consisting of pure CR-SPLIT, pure REPEAT-OBS, pure dither for both UVIS and IR, along with IR REPEAT-OBS plus dither associations. 3/18/2018 108
COS CALCOS Version 2. 4 has been delivered for OPUS Build 2008. 3. – This version of CALCOS has been tested using thermal vac (TV) data prior to delivery to OPUS. – Regression testing performed by OPUS relies on the SMGT datasets. These datasets contain blank science arrays, but complete headers. – OPUS regression testing has validated that 97% of all the COS SMGT data can be processed through the entire calibration pipeline system from telescope to delivery to the end user. • The only failures coming from the use of shared wavecals. – The COS Pipeline Verification Team processes the TV data to validate the algorithms used in CALCOS for the calibration. 3/18/2018 109
COS The COS PVT has reported: – Functional testing has been completed successfully for CALCOS. – Verification of the pipeline products based on assessment of the calibrated data and the algorithms has been performed using TV data for at least 8 of the 20 modules in CALCOS. The data used for performing these tests include: – The TV data from 2006 with more than 2100 exposures, covering the majority (if not all) observing modes. – The SMGT data with about 40 associations of both ACCUM and TIME-TAG data taken by both NUV and FUV channels. 3/18/2018 110
OPUS 2008. 4 Work continues on CALCOS, with only a couple PRs which were resolved with the delivery of CALCOS v 2. 5 for OPUS 2008. 4 – CALCOS should become an STSDAS package. (PR 60180) – Reference file handling for wavelength calibration (PR 60653) – Use of science exposure SPT for product SPT file (PR 60708) Recent TV testing of WFC 3 has highlighted the need to make some modifications to CALWF 3 to support the instrument during SMOV. The following OPRs were resolved with the delivery of CALWF 3 V 0. 99 for OPUS 2008. 4. – Cosmic-ray rejection algorithm updates (PR 60727, 60710, 60564) – Produce ‘drz’ files (PR 60674) 3/18/2018 111
OPUS 2008. 4 The repair of ACS will return it to an operational state, and changes will be delivered for testing under 2008. 4 to support ACS SMOV activities: – Support the new commanded gain values for ACS (PR 60729) – Corrections to cosmic-ray rejection (PR 60727, 60710) 3/18/2018 112
Multi. Drizzle No issues are expected for pipeline use of Multidrizzle during SMOV. Multi. Drizzle supports all current instruments imaging modes for ACS, STIS, NICMOS, and WFPC 2, as well as WFC 3 UVIS and IR images. Multidrizzle will only be used in the ACS and WFPC 2 pipelines during SMOV, but not for WFC 3. – – – 3/18/2018 It will not be turned on for WFC 3 pipeline use due to the fact that on-orbit calibrations will need to be performed in order to generate accurate enough distortion models for WFC 3. Verified distortion-correction reference files will be generated by the WFC 3 Instrument team based on calibrations taken in Nov 29 for UVIS and Dec 3 for IR. SMOV calibration activities will still be able to use any new reference files generated from on-orbit data using the locally installed version of Multidrizzle. Pipeline use of Multi. Drizzle for WFC 3 can be added to OPUS as early as OPUS 2009. 1. 113
Post-SMOV Work continues on CALWF 3 based on the results of TV testing of the IR channel to update the following processing steps: • the IR reference pixel subtraction (PR 60657) • the IR non-linearity correction (PR 60659) A number of issues have been identified for COS and even STIS which should not affect SMOV support. These issues have been given a low priority and will be resolved in time for delivery to OPUS 2009. 1. – COS: Trailer file handling may need to be revised based on experience during SMOV. – STIS: Zero exposure time members of STIS associations disappear from the calibrated product (PR 60326) – STIS: CALSTIS should use spectral order when saving the gross count rate (PR 60327) There will additional issues which come up during SMOV, and those will be prioritized based on the impact to SMOV activities. 3/18/2018 114
Routine Maintenance After SM 4 Significant testing has been performed to verify that data taken in the most common modes from each instrument will process successfully through the entire pipeline; from raw telemetry through calibration to archive ingest and retrieval from OTFR. However, issues with unexpected situations will arise during SMOV which will require immediate calibration software fixes, and a procedure will be in place to address these issues. Those isolated calibration pipeline problems which prevent the completion of processing and delivery of data to PIs will be worked with the highest priority during SMOV by SSB. The SSB developer will assess whether the problem arises from: – – – a software bug, reference file problem (which may or may not require a software change), or input file formatting issue (which may still require a software change). For fixes which require calibration software changes: 1. data causing failure will be provided to SSB 2. software will be revised to address the issue 3. functional testing will be performed by SSB along with testing against the problem data to verify that the problem was adequately resolved while still successfully processing the functional test data. 4. 3/18/2018 new code will be delivered to OPUS using standard mechanism 115
Routine Maintenance After SM 4 Any issue identified as a reference file problem will be reported to the instrument team for resolution, and any relevant software change will be verified using the procedure outlined here. Any issue involving the input file format will be reported to OPUS for discussion and resolution, and any relevant software change will be verified using the procedure outlined here. For those issues which do not prevent the processing of data or impede the deliver of data to the PIs: OPRs will be filed, and the work will be prioritized using current methods and criteria. – 3/18/2018 Such issues might include errors in keywords or interpretation of association tables. 116
