 ***************************************************************************
 *
 * $Log: StTPCReader.h,v $
 * Revision 1.7  2004/03/10 05:59:04  jeromel
 * Implement SetSequenceMerging(). See comment in St_tpcdaq_Maker
 *
 * Revision 1.6  2004/03/04 21:51:27  ward
 * Replaced MERGE_SEQUENCES with a StDAQMaker chain parameter, as suggested by Landgraf and Lauret.
 *
 * Revision 1.5  2004/01/23 16:06:43  jeromel
 * Added friend class for FCF
 *
 * Revision 1.4  2003/04/29 16:22:44  perev
 * non TPCoriented cleanup
 *
 * Revision 1.3  2002/10/13 20:43:36  ward
 * Support for decoding DAQ100 data and writing it into a table.
 *
 * Revision 1.2  2000/07/13 22:29:52  perev
 * Return kStErr when TPC data is not in event.
 *
 * Revision 1.1  2000/06/12 15:12:27  perev
 * SVT + cleanup
 *
 *
