Detailed Description

Generate gain-calibration-like files.

Generate raw data files that mimics the one we'll get from the online gain calibration procedure.

We start from one set of gain values, and one set of pedestal values, to be found in the OCDB (generated e.g. with AliMUONCDB class)

We then use those gains and to generate n sets of pedestal values, that we store in OCDB in runs = [firstRunNumber+1,...firstRunNumber+n-1]

Then we loop from 0 to n-1, and for each, we generate a pedestal file, using AliMUONPedestalEventGenerator, where the pedestals used are those stored in the previous step.

Output files are supposed to be processed by the MUONTRKda (gain part) to produce 4 (one per LDC) ascii files (with computed gain values), that in turn will be processed by the Shuttle to put gain values in the OCDB. Those last gains in OCDB can be then compared with the ones generated in the first step, to check that everything is OK in the whole procedure.
