**********************************************************************************/
* VZERO Detector Algorithm used for tuning FEE parameters *
* *
* This program reads data on the LDC *
-* It cumulates fBB and fBG flags, populates local "./V0_Tuning1.dat" *
-* file and exports it to the FES. *
+* It cumulates fBB and fBG flags, populates local "./V0_ChannelDelayTuning.dat" *
+* file, exports it to the FES, and stores it to DAQ DB *
* 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. *
