18 * VZERO Detector Algorithm used for tuning FEE parameters *
20 * This program reads data on the LDC *
21 * It cumulates fBB and fBG flags, populates local "./V0_Tuning1.dat" *
22 * file and exports it to the FES. *
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. *
