2 EMCAL DA for online calibration: for pedestal studies
4 Contact: silvermy@ornl.gov
7 Number of events needed: ~1000
8 Frequency: expect to run this once per day initially
9 (maybe less frequent later)
10 Input Files: argument list
11 Output Files: RESULT_FILE=EMCALPED.root, to be exported to the DAQ FXS
12 fileId: FILE_ID=EMCALPED
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]
19 This process reads RAW data from the files provided as command line arguments
20 and save results (class itself) in a file (named from RESULT_FILE define

25 #define FILE_ID "pedestals"
