17* *
18* VZERO Detector Algorithm used for tuning FEE parameters *
19* *
20* This program reads data on the LDC *
6a2679b5 21* It cumulates mean ADC responses , populates local "./V0_Tuning2.dat" file *
22* and exports it to the FES. * * *
8318157a 23* We have 128 channels instead of 64 as expected for V0 due to the two sets of *
24* charge integrators which are used by the FEE ... *
25* The program reports about its processing progress. *
