22580691 2 EMCAL DA for online calibration: for pedestal studies
3b5beac9 3
4 Contact: silvermy@ornl.gov
22580691 5 Run Type: PEDESTAL
6 DA Type: LDC
07cc7773 7 Number of events needed: ~1000
22580691 8 Frequency: expect to run this once per day initially
9 (maybe less frequent later)
3b5beac9 10 Input Files: argument list
22580691 11 Output Files: RESULT_FILE=EMCALPED.root, to be exported to the DAQ FXS
12 fileId: FILE_ID=EMCALPED
3b5beac9 13
22580691 14 Trigger types used: at least for now, all events in special PEDESTAL run
15 (physics, calibration, systemSoftwareTrigger, detectorSoftwareTrigger)
16 [When we have real data files later, we may restrict this further]
