3TPCda_pedestal.cxx - calibration algorithm for TPC pedestal runs
4
510/06/2007 sylvain.chapeland@cern.ch : first version - clean skeleton based on DAQ DA case1
fee88714 619/10/2007 christian.lippmann@cern.ch : Possibility to write output to ASCII file
724/10/2007 christian.lippmann@cern.ch : Including pedestal calibration for time bins
823/11/2007 christian.lippmann@cern.ch : Fix in order to avoid streamer problems in case of
9 invalid ROOTSTYS. The famous magic line provided by Rene.
1028/11/2007 christian.lippmann@cern.ch : TPC mapping file is read from DaqDetDB

c12208b8 14This process reads RAW data from the files provided as command line arguments
15and save results in a file (named from RESULT_FILE define - see below).
