Minutes

Attendees: Simon T., Alex B., Justin S., Curtis M., Will M., Nacer, Alex A???, Mark I., Mark D., Luke R., Eugene C., Beni Z.

• The next monitoring pass awaits changes to the tracking code by Simon T. Changes to the BCAL reconstruction are probably not going to be ready for a month or two.
  • We typically run over the first 5 files of each run -- Beni is working on possibly reconfiguring the TOF time-walk correction, but he needs much more data (maybe 40 files/run). We can use the monitoring pass to check any changes.
• The first analysis pass over the data is imminent; waiting for some plugin cleanup.
• BCAL: Will M. has made progress in matching MC energy/timing response to real data.
• TOF: Beni is working on efficiencies
• Tagger: Nathan and Alex B. are working on clusterization of hits.
• Alex B. warned not to require the TAGM TDC for early runs -- does not affect REST files.
• Many groups (TOF, Tagger, BCAL) will need channel-by-channel discriminator thresholds - Alex S. is aware...
• The latest simulation pass (sim1.1) has been completed, 8000 jobs with 25000 events each = ~1% of amount of the real data. Information about the simulation can be found here
