6472f844 24// It gets High Voltage values for a given run from DCS and Pedestal values from DAQ
25// and writes them as Calibration MetaData into OCDB/VZERO/Calib/Data
26// It also retrieves FEE parameters from DCS archive
27// and writes them as Trigger MetaData into OCDB/VZERO/Trigger/Data
28// (to be used for trigger simulation)
