 * $Log: StEStructHAdd.h,v $
 * Revision 1.6  2010/06/23 22:33:45  prindle
 * In HAdd we distinguish between the parent distributions of the
 *    two particles.
 *   In Support I fixed a number of problems in the Pt correlation section.
 *
 * Revision 1.5  2010/03/02 21:48:30  prindle
 *   Fix addDensities (for checking pair cuts)
 *   Lots of small changes
 *
 * Revision 1.4  2008/05/01 23:46:40  prindle
 *   Changed to use TH1D and TH2D (instead of TH1 and TH2) in some places so
 * we can use GetObject method to enforce type checking. Found I had missed
 * duplicating a \phi_\Delta row in one case. Also added a method to include
 * sum of pairdensity histograms in output file.
 *
 * Revision 1.3  2007/11/26 20:07:17  prindle
 * Modified to average \Delta\rho/sqrt(\rho) over z-bins (if more than one z-bin
 * present for given centrality. Note: I weight by number of tracks, not number of
 * pairs. This is important when we are also combining different centralities (which
 * I do by combining centrality tag with z-bin tag in macro/addCentralities.)
 *
 * Scale mixed histograms by number of events. Integral of \Delta\rho need not be 0.
 *
 * delete items that are created and valgrind complained were lost. (Not a big deal
 * since macro is run once)
 *
 * [Still need to commit StEStructHAdd.cxx which cvs complained that check-update failed.]
 *
 * Revision 1.2  2006/04/06 01:09:47  prindle
 *   Calculating pt for each cut bin caused changes in HAdd.
 * The splitting of +- into +- and -+ caused changes in Support.
 *
 * Revision 1.1  2004/07/01 00:37:17  porter
 * new code previously my StEStructHelper. Takes hists from correltation
 * pass and builds final ressults.  Also the StEStructHAdd.h is a simple
 * replacemnt for my sumyt.C macro which could be expanded later as needed.
