17 * VZERO Detector Algorithm used for extracting calibration parameters *
19 * This program connects to the DAQ data source passed as argument. *
20 * It computes calibration parameters, populates local "./V0_Ped_Width_Gain.dat" *
21 * file and exports it to the FES. *
22 * The program exits when being asked to shut down (daqDA_checkshutdown) *
23 * or End of Run event. *
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 ... *
