// $Log: StFlowPicoTrack.cxx,v $
// Revision 1.11  2003/01/08 19:26:51  posk
// PhiWgt hists sorted on sign of z of first and last points.
// Version 6 of pico file.
//
// Revision 1.10  2001/12/18 19:22:35  posk
// "proton" and "antiproton" changed to "pr+" and "pr-".
// Compiles on Solaris.
//
// Revision 1.9  2001/12/12 21:36:20  posk
// For Solaris compatability, added: #include <math.h>
//
// Revision 1.8  2001/07/27 01:26:37  snelling
// Added and changed variables for picoEvent. Changed trackCut class to StTrack
//
// Revision 1.7  2001/07/24 22:29:37  snelling
// First attempt to get a standard root pico file again, added variables
//
// Revision 1.6  2000/12/12 20:22:06  posk
// Put log comments at end of files.
// Deleted persistent StFlowEvent (old micro DST).
//
// Revision 1.5  2000/12/10 02:01:13  oldi
// A new member (StTrackTopologyMap mTopology) was added to StFlowPicoTrack.
// The evaluation of either a track originates from the FTPC or not is
// unambiguous now. The evaluation itself is easily extendible for other
// detectors (e.g. SVT+TPC). Old flowpicoevent.root files are treated as if
// they contain TPC tracks only (backward compatibility).
//
// Revision 1.4  2000/10/12 22:46:39  snelling
// Added support for the new pDST's and the probability pid method
//
// Revision 1.3  2000/09/15 22:51:32  posk
// Added pt weighting for event plane calcualtion.
//
// Revision 1.2  2000/09/05 17:57:12  snelling
// Solaris needs math.h for fabs
//
// Revision 1.1  2000/09/05 16:11:36  snelling
// Added global DCA, electron and positron
//
//
