+*                                                                                 *
+* This program reads data on the LDC                                              *
+* It cumulates mean ADC responses ,  populates local                              *
+*                                   "./V0_IntegrationGateTuning.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 ...                                *
