16* *
17* VZERO Detector Algorithm used for extracting calibration parameters *
18* *
03e924d7 19* This program connects to the DAQ data source passed as argument. *
bb80ae5b 20* It computes calibration parameters, populates local "./V0_Ped_Width_Gain.dat" *
21* file and exports it to the FES. *
03e924d7 22* The program exits when being asked to shut down (daqDA_checkshutdown) *
c2d54b4c 23* or on End of Run event. *
bb80ae5b 24* We have 128 channels instead of 64 as expected for V0 due to the two sets of *
25* charge integrators which are used by the FEE ... *
