  EMCAL DA for online calibration: for LED studies
  
  Contact: silvermy@ornl.gov
  Run Type: PHYSICS or STANDALONE
  DA Type: MON 
  Number of events needed: continously accumulating for all runs, rate ~0.1-1 Hz
  Input Files: argument list
  Output Files: RESULT_FILE=EMCALLED.root, to be exported to the DAQ FXS
  fileId:  FILE_ID=EMCALLED    
  Trigger types used: CALIBRATION_EVENT (temporarily also PHYSICS_EVENT to start with)
  [When we have real data files later, we should only use CALIBRATION_EVENT]
