// $Log: StFtpcFastSimu.hh,v $
// Revision 1.17  2004/02/12 19:38:46  oldi
// Removal of intermediate tables.
//
// Revision 1.16  2004/01/28 02:04:43  jcs
// replace all instances of StFtpcReducedPoint and StFtpcPoint with StFtpcConfMapPoint
//
// Revision 1.15  2003/10/10 12:36:15  jcs
// implement new FTPC geant volume id method
// initialize counters and arrays to zero
// replace many int,float's wiht Int_t,Float_t
//
// Revision 1.14  2002/09/16 12:43:22  jcs
// replace large statically dimensioned arrays with dynamically dimensioned arrays
//
// Revision 1.13  2001/03/19 15:52:47  jcs
// use ftpcDimensions from database
//
// Revision 1.12  2001/01/25 15:25:49  oldi
// Fix of several bugs which caused memory leaks:
//  - Some arrays were not allocated and/or deleted properly.
//  - TClonesArray seems to have a problem (it could be that I used it in a
//    wrong way in StFtpcTrackMaker form where Holm cut and pasted it).
//    I changed all occurences to TObjArray which makes the program slightly
//    slower but much more save (in terms of memory usage).
//
// Revision 1.11  2001/01/08 17:10:04  jcs
// move remaining constants from code to database
//
// Revision 1.10  2000/11/24 15:02:33  hummler
// commit changes omitted in last commit
//
// Revision 1.8  2000/09/18 14:26:49  hummler
// expand StFtpcParamReader to supply data for slow simulator as well
// introduce StFtpcGeantReader to separate g2t tables from simulator code
// implement StFtpcGeantReader in StFtpcFastSimu
//
// Revision 1.7  2000/08/03 14:39:00  hummler
// Create param reader to keep parameter tables away from cluster finder and
// fast simulator. StFtpcClusterFinder now knows nothing about tables anymore!
//
// Revision 1.6  2000/02/04 13:49:42  hummler
// upgrade ffs:
// -remove unused fspar table
// -make hit smearing gaussian with decent parameters and static rand engine
// -separate hit smearing from cluster width calculation
//
// Revision 1.5  2000/02/02 15:40:08  hummler
// make hit smearing gaussian instead of box-shaped
//
// Revision 1.4  2000/02/02 15:20:37  hummler
// correct acceptance at sector boundaries,
// take values from fcl_det
//
// Revision 1.3  2000/01/03 12:48:59  jcs
// Add CVS Id strings
