5 - Reference run number :
6 - Run Type: INTEGRATION_GATE_TUNING (not defined yet)
8 - Number of events needed: 500
9 - Input Files: argument list
10 - Output Files: local file V0_IntegrationGateTuning.dat

18 * VZERO Detector Algorithm used for tuning Integration Gates *
20 * This program reads data on the LDC *
21 * It cumulates mean ADC responses , populates local *
22 * "./V0_IntegrationGateTuning.dat" file *
23 * and exports it to the FES. *
24 * We have 128 channels instead of 64 as expected for V0 due to the two sets of *
25 * charge integrators which are used by the FEE ... *
26 * The program reports about its processing progress. *
