// $Log: BrSiParameters.cxx,v $
// Revision 1.1.1.1  2001/06/21 14:55:00  hagel
// Initial revision of brat2
//
// Revision 1.3  2001/05/31 01:46:34  cholm
// Second rewamp of this directory.  All RDO modules use the common
// BrMultRdoModule, and they both write BrMultRdo Objects.  Also introduced
// ABC for Br[Tile|Si][Parameters|Calibration] since they have a lot in common,
// and the code can be made more efficient this way.
//
// A possible further thing to do, is to make an ABC for the CentModules, and
// the corresponding calibration modules, since they are very VERY similar.
// However, the current module BrMultCentModule is in the way.  Need to talk
// to Steve about that.
//
// Revision 1.2  2001/04/06 19:56:41  cholm
// Added some new parameteres to read from  ASCII file.
//
// Revision 1.1  2001/01/29 20:12:30  cholm
// Changed name of BrDetectorParamsMultSi to BrSiParameters since this will
// be the new naming scheme of classes in BRAT 2. The idea is to have different
// parts of a class name located at specific point in the name. At some point,
// BrDetectorParams will be renamed to BrParameters.
//
// Revision 1.5  2000/08/17 14:50:43  hito
// *** empty log message ***
//
// Revision 1.4  2000/07/26 22:08:37  hito
// Mapping of digitization for si and tile were changed to reflect the raw data
// and the change in gbrahms.
//
// Revision 1.3  2000/04/06 20:21:12  cholm
// Corrected bugs in BrDigitizeMultSi
//
// Revision 1.2  2000/03/21 21:22:19  cholm
// Several changes: A few hacks where needed to compile on Digital Unix, noticably in my - Christian Holm - classes for the DB and Exceptions. Proberly still need to do something to some of Konstantins stuff. Also, I removed a lot of warnings fromt the compiler, by teddying up the code. Several places, old C-style indecies in for loops were assumed. Corrected. Unused variables have been commented out.
//
// Revision 1.1  2000/03/17 16:17:55  cholm
// Added classes BrDigitizeMultSi and BrDetectorPramMultSi for GBRAHMS simulations
//
//
