* VZERO Detector Algorithm used for extracting calibration parameters *
* *
-* This program reads the DDL data file passed as argument using the monitoring *
-* library. *
+* 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. *
+* file, exports it to the FES, and stores it into DAQ DB *
+* The program exits when being asked to shut down (daqDA_checkshutdown) *
+* or on 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 ... *
-* The program reports about its processing progress. *
