8  * Description: part of STAR HBT Framework: StHbtMaker package
9  * HbtEvent is the "transient microDST" Objects of this class are
10  * generated from the input data by a Reader, and then presented to
11  * the Cuts of the various active Analyses.

20  * New event constructor to find V0 daughters informations(helix for average
21  * separation calculation)
22  *
23  * Revision 1.18 2002/03/21 18:49:31 laue
24  * updated for new MuDst reader
25  *

27  * l3 trigger algorithm added
28  *
29  * Revision 1.14 2001/06/21 19:15:45 laue
30  * Modified fiels:
31  * CTH.hh : new constructor added
32  * StHbtEvent, StHbtKink, StHbtTrack : constructors from the persistent
33  * (TTree) classes added
34  * StHbtLikeSignAnalysis : minor changes, for debugging

41  * StHbtTTreeV0.cxx StHbtTTreeV0.h StHbtVector.hh
42  *
43  * Revision 1.13 2001/06/04 19:09:52 rcwells
44  * Adding B-field, run number, and improved reaction plane functionality
45  *
46  * Revision 1.12 2001/05/25 23:23:59 lisa
47  * Added in StHbtKink stuff
48  *
49  * Revision 1.11 2001/05/15 15:30:16 rcwells
50  * Added magnetic field to StHbtEvent
51  *
52  * Revision 1.10 2000/08/31 22:31:31 laue
53  * StHbtAnalysis: output changed (a little bit less)
54  * StHbtEvent: new version, members for reference mult added
55  * StHbtIOBinary: new IO for new StHbtEvent version
56  * StHbtTypes: TTree typedef to StHbtTTree added

58  *
59  * Revision 1.9 2000/05/25 21:54:16 laue
60  * RotateZ implemented. Rotates momentum and helix around the z axis
61  *
62  * Revision 1.7 2000/02/18 21:32:23 laue
63  * franksTrackCut changed. If mCharge is set to '0' there will be no cut
64  * on charge. This is important for front-loaded cuts.
65  *
66  * copy constructor implemented for StHbtEvent, StHbtTrack and StHbtV0.
67  *
68  * franks1HistoD.cxx franks1HistoD.h franks2HistoD.cxx franks2HistoD.h
69  * removed. We can now (CC5 on Solaris) use the versions (no D)
70  *
71  * Revision 1.6 1999/09/16 18:47:59 lisa
72  * replace placeholder HbtV0Track stuff with Helens StHbtV0 classes
73  *
74  * Revision 1.5 1999/09/03 22:39:15 lisa
75  * Readers now MUST have Report() methods and MAY have WriteHbtEvent() methods
76  *
77  * Revision 1.4 1999/07/19 14:24:06 hardtke
78  * modifications to implement uDST
79  *
80  * Revision 1.3 1999/07/06 22:33:22 lisa
81  * Adjusted all to work in pro and new - dev itself is broken
82  *
83  * Revision 1.2 1999/06/29 17:50:27 fisyak
84  * formal changes to account new StEvent, does not complie yet
85  *
