TPCda_pedestal.cxx - calibration algorithm for TPC pedestal runs
10/06/2007 sylvain.chapeland@cern.ch : first version - clean skeleton based on DAQ DA case1
-19/10/2007 christian.lippmann@cern.ch : Possibility to write output to ASCII file
-24/10/2007 christian.lippmann@cern.ch : Including pedestal calibration for time bins
-23/11/2007 christian.lippmann@cern.ch : Fix in order to avoid streamer problems in case of
- invalid ROOTSTYS. The famous magic line provided by Rene.
-28/11/2007 christian.lippmann@cern.ch : TPC mapping file is read from DaqDetDB
contact: marian.ivanov@cern.ch
+
This process reads RAW data from the files provided as command line arguments
and save results in a file (named from RESULT_FILE define - see below).
