16* *
17* AD Detector Algorithm used for extracting calibration parameters *
18* *
19* This program connects to the DAQ data source passed as argument. *
20* It computes calibration parameters, populates local "./AD0_Pedestals_On.dat" *
21* file, exports it to the FES, and stores it into DAQ DB *
22* The program exits when being asked to shut down (daqDA_checkshutdown) *
23* or on End of Run event. *
24* We have 32 channels instead of 16 as expected for AD0 due to the two sets of *
25* charge integrators which are used by the FEE ... *
