Next Generation Instruments ¯ A near-infrared imager and spectrometer, optimized for MCAO, are likely the next set of instruments to be built within the Gemini program ¯ FLAMINGOS-2 will provide some 1 -2. 5 µm slit spectroscopic capability as well ¯ Imager Sample MCAO PSF across ~2 arcmin FOV ± Nominally 2 x 2 mosaic of 20482 arrays ± 1 -2. 5 µm Rockwell devices, either HAWAII-2 or Cd. Zn. Te (requires detector development) ±

MCAO Optimized Spectrometer ¯ Baseline design stems from current GIRMOS d-IFU tech study occurring at ATC and AAO ~2 arcmin deployment field ± 1 - 2. 5 µm coverage using 6 detectors ± IFUs ± • • 12 deployable IFUs total ~0. 03” spatial sampling ~1 x 1” field for each IFU R ~ 6000

Demonstration Science Programs

Hokupa’a Demonstration Science - Plan ¯ K’, H, CO and K-cont imaging of in and around the Galactic Centre to study the distribution of stellar populations vs. distance from Sgr A* 6 -8 fields in the GC ± 2 control fields 3 arcmin along plane ± 2 fields in “Arches” 10 arcmin North ±

Hokupa’a Demonstration Science Results ¯ Overview of data: FWHM (H, K’) = 0. 1” - 0. 15” ± 9 fields of 20”x 20” mapped in H and K’ ± 6 min (K’) / 12 min (H) to 40 min per field ± CO and K-cont on most fields ±

OSCIR Demonstration Science: Planning ¯ Four options considered for 10 um deep field ± ‘Blank’ field survey - rejected • FOV too small given mid-IR source counts; sensitivity shallow compared with ultra-deep ISO surveys ± X-ray selected fields - rejected • No suitable sample of reliable hard X-ray sources SCUBA-selected cluster fields ± SCUBA-selected Hz. RG fields ± • Strategy is to observe the brightest from both cluster and Hz. RG lists, four targets in total • Some are unknown quantities in the mid-IR; one is a bright-ish ISOCAM detection; one has a good redshift, and there is the potential for serendipity with some less identified (and perhaps higher redshift) counterparts

OSCIR Demonstration Science: Results ¯ OSCIR DS observations not yet taken place… …. but encouraging results (sensitivity, image quality & PSF) from first engineering run

Quick. Start Service Observing

Quick. Start Overview ¯ Quick. Start enables scientific use of Hokupa'a/QUIRC and OSCIR prior to the start of normal operations The aims are to exercise proposal, planning and operational procedures, refine telescope and instrument performance, train support staff and get data out into the community ± Proposals were submitted via the National TACs and ITAC in (what will become) the normal process ± Successful applications are being executed by Gemini staff in a service mode ± • Phase II detailed definition performed by Gemini Contact Scientists (in consultation with PI if necessary) • Planning and execution of later Quick. Start blocks will have direct involvement of National Office support staff from US, UK and Canada • (Manual) data processing follows pipeline procedures

Quick. Start Proposal Statistics ¯ Oversubscription assumes 420 hr available and nominal partner shares ± Likely to be underestimate as some proposals neglected to include significant overheads

0. 065 arcsec at 1. 65 um

Hokupa’a Quick. Start Performance ¯ Performance is consistent with expectations Including AO correction as a function of observing conditions and WFS target brightness, overheads ± Will refine web information before Cf. P ± ¯ Observing efficiency is consistent with the goal for Quick. Start ± 30% ‘shutter-open’ (cf 15% during dedication imaging)

Semester 2001 A Schedule (1 Feb - 31 July 2001) ¯ Announcement and Call for Proposals - 1 Sept ± NIRI final (on-telescope) Acceptance Test (AT) continues • NIRI passed pre-ship lab AT in May • Initial HBF lab characterisation occurred in June-July ¯ NTAC deadline for 2001 A normal cycle: end Sept ± Specific date varies slightly from partner to partner ¯ Ranked proposals due at Gemini: 22 Nov ¯ ITAC: 13 Dec ¯ Semester 2001 A runs 1 Feb - 31 July

Top-Level Operational Constraints for 2001 A ¯ All capabilites are made available in shared-risks mode ¯ Baseline instrument availability ¯ Facility: NIRI ¯ Visitor: Hokupa’a+QUIRC, OSCIR ¯ Not CIRPASS, GMOS, other visitor instruments ¯ Operational modes ¯ Queue ¯ Classical ¯ May also be partner-run service mode ¯ Queue & classical modes schedules as blocks ¯ Permit observations of non-sidereal objects ¯ 30 -50% engineering time

Planned 2001 A Phase II Preparation ¯ Require Observing Tool (OT) for NIRI queue observations ± Must contain high level of functionality to minimise support staff effort • • ± Define NIRI, GCAL and telescope configurations Define telescope sequences Field, position sequence and time visualisation Develop OT library content of commonly-executed configurations, sequences and calibrations to ease user learning curve Beta-2 version was tested extensively; required development is well-understood ¯ Require database to hold Phase II programs with simple query and reporting capabilities

Observing Tool Beta-2 Features ¯ Target, offset and WFS positions, including graphical representations. ¯ Detailed representation of NIRI OIWFS and vignetting.

Gemini Requirements Update ¯ Available instruments semester 2001 A: ± ± ± NIRI - near infrared OIWFS most likely only at f/14 UH AO - no OIWFS, NGS limiting magnitude R~16 OSCIR - no OIWFS GMOS CIRPASS - no OIFWS ¯ Semester 2001 A Proposals deadline was 30 September 2000. Use of GSC 1 ± Phase-II we expect to use GSC 2 ±

Gemini Requirements Update ¯ Until final delivery of GSC 2. 2 (January 2001), we will continue to use a combination of GSC 1, GSC 2. 1. X, USNO and Hipparcos/Tycho to support guide star selections in future semesters. ¯ Once GSC 2. 2 is delivered, it will be made available via our server to successful queue/classical observers, i. e. those who have been awarded time and are in Phase II. ¯ AO programs require good astrometrics, proper motions, and classification to select adequate AOGS: R<16 -17 with known proper motions and not too extended.

DSS II ¯ CADC delivered two copies in one band (red) to Gemini ~August 1999 ¯ Gemini does not have a large enough jukebox to house all DSS II disks. Working a deal with NOAJ. ¯ ~1/3 of DSSII is installed in Subaru jukebox and accessible via our secure network to Gemini since May 2000. ¯ MOU has been signed two weeks ago by Directors of Subaru and Gemini. Green light (lawyers) to load rest of CDROMs in Subaru jukebox in early November. ¯ For political reasons, good to have % of sky covered. ¯ From users perspective: quick way of knowing if area is included in delivered survey.

GSC II ¯ Delivery to Gemini started September 1999 ¯ Still not widely used within Gemini because of decrease sky coverage compared with existing catalogs (GSC 1, USNO, 2 MASS). “Customers” (read: proposal writers and observers) prefer to use catalogs that will provide them with all sky coverage. ¯ Fluxes in standard photometric system. ¯ For political reasons: good to know % of sky covered. ¯ From an users perspective: Useful to know if star/area is contained in delivered catalog (maybe a mute point now but…)
