/*

HMPID DA for online calibration

Contact: Levente.Molnar@ba.infn.it, Giacomo.Volpe@ba.infn.it
Link: http://richpc1.ba.infn.it/~levente/Files4Public/ValidateHmpidDA/
Run Type: PEDESTAL -- but we select on the PHYSICS_EVENTS in th HMPIDda.cxx
DA Type: LDC
Number of events needed: 1000 events
Input Files: Raw pedestal file, EXTERNAL config file: HmpidSigmaCut.txt on both HMPID LDCs
Output Files: 14 txt files including pedestal values
Trigger types used: PEDESTAL RUN (selecting on PHYSICS_EVENT)
