108  * $Log: StMuPrimaryVertex.h,v $
109  * Revision 1.11 2017/05/17 16:03:04 smirnovd
110  * StMuPrimaryVertex: Passing pointer by reference is pointless
111  *
112  * Revision 1.10 2017/04/17 19:19:43 smirnovd
113  * [Cosmetic] Whitespace adjustments
114  *
115  * Revision 1.9 2012/09/16 21:58:16 fisyak
116  * Make use of Tpc West and East Only no. of tracks
117  *
118  * Revision 1.8 2012/05/07 14:47:06 fisyak
119  * Add handles for track to fast detector matching
120  *
121  * Revision 1.7 2011/10/17 00:19:14 fisyak
122  * Active handing of IdTruth
123  *
124  * Revision 1.6 2011/04/08 01:25:51 fisyak
125  * Add branches for MC track and vertex information, add IdTruth to tracks and vertices, reserve a possiblity to remove Strange MuDst
126  *
127  * Revision 1.5 2009/12/24 21:19:31 tone421
128  * Added StMuPrimaryVertex::nBTOFMatch()
129  *
130  * Revision 1.4 2007/09/18 02:29:58 mvl
131  * Added basic printing functionality. For convenience and to assist data consistency checks
132  *
133  * Revision 1.3 2006/04/25 08:27:43 mvl
134  * Added members and getters for mean-dip and chisquared value
135  *
136  * Revision 1.2 2005/08/19 19:46:05 mvl
137  * Further updates for multiple vertices. The main changes are:
138  * 1) StMudst::primaryTracks() now returns a list (TObjArray*) of tracks
139  * belonging to the 'current' primary vertex. The index number of the
140  * 'current' vertex can be set using StMuDst::setCurrentVertex().
141  * This also affects StMuDst::primaryTracks(int i) and
142  * StMuDst::numberOfprimaryTracks().
143  * 2) refMult is now stored for all vertices, in StMuPrimaryVertex. The
144  * obvious way to access these numbers is from the StMuprimaryVertex structures,
145  * but for ebakcward compatibility a function is provided in StMuEvent as well
146  * (this is the only function that works for existing MuDst)
147  *
148  * As an aside, I've also changes the internals of StMuDst::createStEvent and
149  * StMuDst::fixTrackIndices() to be able to deal with a larger range of index numbers for tracks as generated by Ittf.
150  *
151  * BIG FAT WARNING: StMudst2StEventMaker and StMuDstFilterMaker
152  * do not fully support the multiple vertex functionality yet.
153  *
154  * Revision 1.1 2005/07/15 21:45:09 mvl
155  * Added support for multiple primary vertices (StMuPrimaryVertex). Track Dcas are now calculated with repect to the first vertex in the list (highest rank), but another vertex number can be specified. Tarcks also store the index of the vertex they belong to (StMuTrack::vertexIndex())
