+* 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.                                                 *
+* 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.                              *
+*                                                                                 *
