/*

TPCda_pulser.cxx - calibration algorithm for TPC pulser events

10/06/2007  sylvain.chapeland@cern.ch :  first version - clean skeleton based on DAQ DA case1
30/09/2007  haavard.helstrup@cern.ch  :  created pulser DA based on pedestal code

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).
