Installed Folders By default, ATHENA distribution kit from production team is used at Tier Installed Folders By default, ATHENA distribution kit from production team is used at Tier centers (option –KITDIR to point wanted kit location). If required Atlas. Production release is not installed on ATHENA kit, corresponding release will be installed under Atlas. Production in installation area (example on slide 10). Normally, one will see: • cmthome : requirement file and initial setup scripts; • Muon. Spectrometer : contain checkout packages; • Install. Area : contain libraries and links for user/checout packages; • data 08 list : contain 2008 data file lists; • run. Ctrl : control datacard and full setup script; • job : Scripts to process data.

Processing Cosmic Ray Data Two scripts to process data under fold job. run_using_default : Processing Cosmic Ray Data Two scripts to process data under fold job. run_using_default : read data file directly from its stored area, where CERN read from CASTOR, BNL and AGLT 2 read from DCACHE, settings are default no writing ESD. run_using_local_disk : copy data files from CASTOR or DCACHE to local area (/tmp/username), where using DCACHE or CASTOR is demonstrated. Both script accept data input and number events to be processed as shown: Process cosmic ray under installation area: mkdir test; cd test; . . /job/run_using_local_disk ! 10 will get Calibration.

Muon Calibration and AA Ntuple • Only MUON calibration NTUPLE will be produced officially Muon Calibration and AA Ntuple • Only MUON calibration NTUPLE will be produced officially in production, where MUON (AA) NTUPLE is not the case. It is recommended that MUON calibration NTUPLEs are used for analysis. • Recently, MOORE tracking are added into MUON calibration NTUPLE. , where Muonboy tracking is not in 14. 5. 0. 1 but has been put in. Segments from Muonboy are still not available but will be so in the near future. Useful Documents 1. Muon calibration ntuple documents : https: //twiki. cern. ch/twiki/bin/view/Atlas/Muon. Calib.

Useful Tools for Calibration Ntuple Many tools to look calibration NTUPLEs, if you want Useful Tools for Calibration Ntuple Many tools to look calibration NTUPLEs, if you want to use those tools, talk to MUON calibration people. For instance Ed Diehl has provided ROOT muonfixedid class to find a hit belongs to which MUON station. In muon calibration NTUPLE, hit ID is muonfixedid where detector type, station, eta and phi are coded as single number. To understand hit ID, one needs to decode it. Existing ROOT muonfixedid class does for you, get it from : ~daits/public/scripts/muonfixedid. h ~daits/public/scripts/checknt. sh to check and merge calibration NTUPLE (from Ed Diehl). ……

Prod. Muon. Rec, user will be able to install ATHENA, checkout packages, and compile packages after modifications. Also raw data file lists are given! Installed scripts run_using_default and run_using_local_disk allow user to process RAW data to produce muon calibration and AA ntuple; • Examples to add user modifications to ATHENA are given; • Scripts generate_cppfile_from_calib. Ntuple and run_cppfile help user to start muon calibration ntuple analysis and process ntuples. • Scripts generate_cppfile_from_muon. Ntuple and run_cppfile help user to start muon AA ntuple analysis and process ntuples. Wish the tutorial helps for your muon works and analysis
