+* *
+* VZERO Detector Algorithm used for tuning FEE parameters *
+* *
+* This program reads data on the LDC *
+* It cumulates mean ADC responses (above pedestals), populates local *
+* "./V0_Tuning2.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. *
