ISOC/SVAC Instrument Analysis Meeting, May 12, 2006 Bye Bye LAT Anders W. Borgland Science Verification, Analysis and Calibrations / ISOC Last evening! Anders W. Borgland 1 ISOC/SVAC Instrument Analysis Meeting, May 12, 2006 Going Anders W. Borgland 2 ISOC/SVAC Instrument Analysis Meeting, May 12, 2006 Going .... Anders W. Borgland 3 ISOC/SVAC Instrument Analysis Meeting, May 12, 2006 Going ..... Anders W. Borgland 4 ISOC/SVAC Instrument Analysis Meeting, May 12, 2006 Gone! Cool truck over here! Anders W. Borgland 5 ISOC/SVAC Instrument Analysis Meeting, May 12, 2006 Reprocessing • Reprocessing: – Hope to start reprocessing at the end of next week early next week! – Will take at least a week to finish – I have an RC-1: – Will debug it over the weekend ...... – With ACD calibrations in the code! – Finally! You will then get calibrated quantities in your ntuples. – Recon.root: – We will keep the recon.root files for this processing – Muon hypothesis: – Will reprocess a subsample using the muon hypothesis » 10M Vertical + 10M Horizontal enough (Johann)? – Context information: – Available in the SVAC ntuple » Extended GEM counters etc – Need to write the documentation ..... • Will make MC for all data taking configurations. Anders W. Borgland 6 ISOC/SVAC Instrument Analysis Meeting, May 12, 2006 Some Issues With The Data • Useful things to know about the data quality: – Linked from the main IA page – I will add more details: – Most issues are with the extended counters • Merit ntuple problem: – JIRA GRINF-29 January 31: – Run ID (and also Event ID) are floats in Merit – Get truncated for data run IDs – Thought this was fixed in EM, but it slipped through :-( – Thanks to Bill for discovering this! – 'Fixed' in GR v9: – RunID and EventId are here integers – But not in current EM! – Emergency solution: – Make them 'double' – Will work for the data we took in April/May – Longer term solution: – Base EM on GR v9 – Need to get GR to use Uint64_t: » All extended counters like sequence number (EventID) are actually 64 bits Anders W.
