// $Log: BrTileCalibration.h,v $
// Revision 1.10  2002/03/02 15:33:39  cholm
// Expanded arrays for more centrality cuts
//
// Revision 1.9  2002/02/04 23:51:44  sanders
// Add setter for detector gains
//
// Revision 1.8  2002/01/06 08:31:01  sanders
// Add Setters for pedestals and pedestal width so that these can
// be changed dynamically for calibrations.
//
// Revision 1.7  2001/12/06 00:33:16  sanders
// Fixed calibrations to obtain average pseudorapidity and geometric
// scaling factor for si and tile elements.
//
// Revision 1.6  2001/11/24 15:42:56  sanders
// Added si and tile calibrations for:
// 1) converting from detector multiplicities to ring dNdEta values
// 2) finding the HIJING weighted ring eta value for a given vertex position
// Both of these calibrations were found doing 8th order polynomial fits
// to functions obtained by taking HIJING particle distributions starting
// from vertex locations between -46cm and +46 cm, in 2 cm steps, and
// checking if the corresponding particles "hit" any of the si or tile
// detectors in the array.
//
// Revision 1.5  2001/11/21 19:12:26  cholm
// Added code for reading SDE centrality calibrations for run 4640
// (and forward?).  See also http://www4.rhic.bnl.gov/~cholm/mult.html. Took
// out the default numbers since they were invalid and not used.
//
// Revision 1.4  2001/11/19 04:09:36  sanders
// Revised calibration modules for 200 GeV (yr 2001) si/tile calibrations.
//
// Revision 1.3  2001/10/08 10:27:25  cholm
// Changed detector calibration data classes to derive from BrCalibration,
// rather than BrParameterElement, since that has been replaced. Impact
// on various modules, and so on.  Some user code may need to be changed to.
//
// Revision 1.2  2001/09/12 15:05:59  cholm
// Varius fixes that was needed for the thing to work properly.  Mistakes on
// my part.  Stupid ones too.
//
// Revision 1.1.1.1  2001/06/21 14:54:59  hagel
// Initial revision of brat2
//
// Revision 1.6  2001/05/31 01:45:06  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 1.5  2001/05/17 11:12:28  cholm
// Added support for reading ASCII calibration files for centrality cuts
// in classes BrTileTmpCalibration and BrSiTmpCalibration.
// Added some preliminary work for using the energy signal rather than the
// multiplicity signal for the centrality determination in classses
// BrTileCentCalModule and BrSiCentCalModule.
//
// Revision 1.4  2001/04/06 19:52:50  cholm
// Updated the temporary class BrTileTmpCalibration, for per ring
// conversion functions.
//
// Revision 1.3  2001/04/02 01:14:22  sanders
// BrRdoMult and BrRdoModuleMult reinstated.  These files develop the joint
// Si+Tile multiplicity.  BrRdoModuleMult now gets it parameters from the
// BrTileRdoModule and BrSiRdoModule classes and is a friend of these classes.
//
// Revision 1.2  2001/03/12 19:03:32  cholm
// Revisted the tile classes. Please note, that these are binary incompatible
// with previous classes. These classes now includes (I believe) all that
// Steve and Hiro recently added to thier working code.
//
// Revision 1.1  2001/01/29 20:43:50  cholm
// Added two modules for making tile calibrations (pedestal and gap), as well
// as a calibration data object foir use with the calibration database. The
// ADC gap module is not complete, and the pedestal module isn't tested.
//
//
