ReprocessingReprocessing
• 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.

Some Issues With The DataSome 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
