*                                                                                 *
* This program connects to the DAQ data source passed as argument.                *
* It computes calibration parameters, populates local "./V0_Ped_Width_Gain.dat"   *            
* file and exports it to the FES.                                                 *
* The program exits when being asked to shut down (daqDA_checkshutdown)           *
* or End of Run event.                                                            *
* We have 128 channels instead of 64 as expected for V0 due to the two sets of    *
* charge integrators which are used by the FEE ...                                *
