SVAC/PVOC&A Meeting, February 6, 2006 Anders W. Borgland 1 Instrument Analysis Activities Anders W. Borgland Science Verification, Analysis and Calibrations / Physics Verification and Optimization Data LAT

SVAC/PVOC&A Meeting, February 6, 2006 Anders W. Borgland 2 LAT Muon Data Is Here! All LAT SVAC muon runs are now: –Reprocessed: –Latest calibrations –Latest EngineeringModel release List of runs: –PDF file with all run numbers –Use only these runs for your analysis!

SVAC/PVOC&A Meeting, February 6, 2006 Anders W. Borgland 3 'Unexpected Features' Two bugs discovered: –Merit ntuple variable 'EvtRun': –Problem discovered by Bijan: »Run number for EvtRun did not always match the real run number –Declared as float instead of (unsigned) int in AnalysisNtuple –Will be incorrect for run numbers in the range we have in real data: »Truncated values –But, is correct for DC2 type runs numbers! –Correct run number is available in the SVAC ntuple: »RunID –ACD tile has wrong thickness: –Row 3, column 4 i.e. tile ID 34. –12 mm instead of 10 mm –Discovered by Eric – confirmed by Joanne –This bug is not in the DC2 geometry: »It was introduced when we made the overlap in the right direction

SVAC/PVOC&A Meeting, February 6, 2006 Anders W. Borgland 4 LAT Data Analysis Three main groups of analyses: –ACD –TKR –CAL Two points: –Analyses very sub-system oriented: –This is what we need to do in the beginning! »Want to make sure we understand the different subsystems when they are integrated.... LAT Data Analysis –But now it's time to do LAT Data Analysis ! –Not a single analysis/talk from Italy! –We miss you guys

SVAC/PVOC&A Meeting, February 6, 2006 Anders W. Borgland 5 Near Future: FSW Flight Software is here! –Power on/off going on right now. –Muons with FSW this week!!!!!!! –Will they look like LATTE muons? :-) LSF: –Data format changes: –LDF becomes LSF –Main difference for you: –Context information »We will get back to you about this –Your SVAC and Merit ntuples will look pretty much the same as now! Pipeline: –We're working hard on getting the pipeline to digest LSF/FSW: –Getting CCSDS packets to offline –Make the pipeline understand if it's LDF or LSF: »We will still take LATTE/LDF data once in a while –A new EngineeringModel release: »LSF reader –'We' means Heather, Bryson, Warren, Eric & Jim!

SVAC/PVOC&A Meeting, February 6, 2006 Anders W. Borgland 6 Summary Calibrated and reprocessed LAT muon data: –Now Available! We need YOU to look at it! –This is the data to analyze for the IA workshop! Final End2End muon runs: –Just before we ship the LAT to NRL LAT DATA ANALYSIS! Instrument Analysis Workshop : –February 27 and 28 –Just before the DC2 kickoff! –Have you registered?
