 *
 * $Log: StEStructBuffer.h,v $
 * Revision 1.5  2011/08/02 20:34:02  prindle
 * More detailed histograms for event mixing.
 *   Buffer: increased mixed events to 4 (from 2)
 *   CutBin: added mode 9 for exploration of p_t space, fixed place in mode 5 where
 *           histogram was written before checking it existed.
 *   OneBuffer: added ZDC coincidence rate to event sorting space.
 *
 * Revision 1.4  2007/01/26 17:17:09  msd
 * Implemented new binning scheme: dEta stored in array with bin centered at zero, dPhi array has bins centered at zero and pi.  Final DEtaDPhi has 25x25 bins with dPhi bin width of pi/12 so all major angles are centered in bins.
 *
 * Revision 1.3  2006/04/04 22:10:12  porter
 * a handful of changes (specific to correlations)
 *  - added StEStructQAHists so that if NOT input frm Maker, each analysis has its own
 *  - used ability to get any max,min val from the cut class - or z-vertex binning
 *  - put z-vertex binning into 1 place
 *  - switched back 1st line of pair cut method to keep pair if good, not to reject if bad.
 *  - Pair cut object is now pointer in correlations
 *  - some diagnostic printouts available from macro
 *  - Duncan's delta-phi binning change
 *
 * Revision 1.2  2005/09/14 17:14:23  msd
 * Large update, added new pair-cut system, added pair density plots for new analysis mode (4), added event mixing cuts (rewrote buffer for this)
 *
 * Revision 1.1  2003/10/15 18:20:46  porter
 * initial check in of Estruct Analysis maker codes.
