18 TPCda_pedestal.cxx - calibration algorithm for TPC pedestal runs
20 10/06/2007 sylvain.chapeland@cern.ch : first version - clean skeleton based on DAQ DA case1
22 contact: marian.ivanov@cern.ch
25 This process reads RAW data from the files provided as command line arguments
26 and save results in a file (named from RESULT_FILE define - see below).
