 * Description: INL correction for all TDIG board channels
 *
 *****************************************************************
 *
 * $Log: StBTofINLCorr.h,v $
 * Revision 1.5  2012/02/11 02:13:23  geurts
 * allow direct access to INL corrections given TDIG-Id
 *
 * Revision 1.4  2009/12/14 19:38:30  dongx
 * - mNValidBoards set by the read-in database entrie instead of a hard-coded number
 * - clean up mNValidTrays and related functions (not needed since previous versions)
 *
 * Revision 1.3  2009/03/04 04:57:36  dongx
 * INL arrays changed from float to short - memory occupied reduced by a factor of 2
 *
 * Revision 1.2  2009/02/13 23:32:52  dongx
 * fixed the crash when no INL table for some board is available
 *
 * Revision 1.1  2009/02/02 21:57:51  dongx
 * first release - Barrel TOF INL correction functions
 *
