  4. Going .....

  5. Gone! Cool truck over here!

  6. 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.

  7. 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

  8. Gone But Not Forgotten!
