8  * Description: part of STAR HBT Framework: StHbtMaker package
9  * Intermediate format for particle. This is built from the
10  * input particle format (e.g. StTrack of StEvent) and presented to
11  * the Analyses for ParticleCuts.

15  * $Log: StHbtTrack.hh,v $
16  * Revision 1.24 2005/07/15 17:40:57 kopytin
17  * initialized mHiddenInfo to null in StHbtTrack()
18  *
19  * Revision 1.23 2003/09/02 17:58:32 perev
20  * gcc 3.2 updates + WarnOff
21  *
22  * Revision 1.22 2003/03/18 14:41:48 kisiel
23  * Bugfix update for the theoretical part of the code. Reverts the changes to the Lednicky weight calculator, as the previuos one had problems with strong interaction
24  *
25  * Revision 1.21 2002/03/21 18:49:31 laue
26  * updated for new MuDst reader
27  *
28  * Revision 1.20 2001/12/14 23:11:30 fretiere
29  * Add class HitMergingCut. Add class fabricesPairCut = HitMerginCut + pair purity cuts. Add TpcLocalTransform function which convert to local tpc coord (not pretty). Modify StHbtTrack, StHbtParticle, StHbtHiddenInfo, StHbtPair to handle the hit information and cope with my code
30  *
31  * Revision 1.17 2001/06/21 19:15:48 laue
32  * Modified fiels:
33  * CTH.hh : new constructor added
34  * StHbtEvent, StHbtKink, StHbtTrack : constructors from the persistent
35  * (TTree) classes added
36  * StHbtLikeSignAnalysis : minor changes, for debugging
37  * StHbtTypes: split into different files
38  * Added files: for the new TTree muDst's
39  * StExceptions.cxx StExceptions.hh StHbtEnumeration.hh
40  * StHbtHelix.hh StHbtHisto.hh StHbtString.hh StHbtTFile.hh
41  * StHbtTTreeEvent.cxx StHbtTTreeEvent.h StHbtTTreeKink.cxx
42  * StHbtTTreeKink.h StHbtTTreeTrack.cxx StHbtTTreeTrack.h
43  * StHbtTTreeV0.cxx StHbtTTreeV0.h StHbtVector.hh
44  *
45  * Revision 1.16 2001/05/25 23:23:59 lisa
46  * Added in StHbtKink stuff
47  *
48  * Revision 1.15 2001/04/05 22:25:15 kisiel
49  * Correct the problems detected by Insure++.
50  *
51  * Revision 1.14 2001/04/03 21:04:36 kisiel
52  *
53  *
54  * Changes needed to make the Theoretical code
55  * work. The main code is the ThCorrFctn directory.
56  * The most visible change is the addition of the
57  * HiddenInfo to StHbtPair.
58  *
59  * Revision 1.13 2000/05/03 17:44:43 laue
60  * StHbtEvent, StHbtTrack & StHbtV0 declared friend to StHbtIOBinary
61  * StHbtParticle updated for V0 pos,neg track Id
62  *
63  * Revision 1.12 2000/04/03 16:21:51 laue
64  * some include files changed
65  * Multi track cut added
66  *
67  * Revision 1.11 2000/02/18 21:32:24 laue
68  * franksTrackCut changed. If mCharge is set to '0' there will be no cut
69  * on charge. This is important for front-loaded cuts.
70  *
71  * copy constructor implemented for StHbtEvent, StHbtTrack and StHbtV0.
72  *
73  * franks1HistoD.cxx franks1HistoD.h franks2HistoD.cxx franks2HistoD.h
74  * removed. We can now (CC5 on Solaris) use the versions (no D)
75  *
76  * Revision 1.10 2000/01/25 17:35:17 laue
77  * I. In order to run the stand alone version of the StHbtMaker the following
78  * changes have been done:
79  * a) all ClassDefs and ClassImps have been put into #ifdef __ROOT__ statements
80  * b) unnecessary includes of StMaker.h have been removed
81  * c) the subdirectory StHbtMaker/doc/Make has been created including everything
82  * needed for the stand alone version
83  *
84  * II. To reduce the amount of compiler warning
85  * a) some variables have been type casted
86  * b) some destructors have been declared as virtual
87  *
88  * Revision 1.9 2000/01/07 22:16:14 laue
89  * missing 'const' in Helix() added
90  *
91  * Revision 1.8 2000/01/06 17:36:38 laue
92  * mNHits changed from 'int' to 'unsigned short'
93  * 'int' is inconsistend with the corresponding getters and setters
94  *
95  * Revision 1.7 1999/09/03 22:39:16 lisa
96  * Readers now MUST have Report() methods and MAY have WriteHbtEvent() methods
97  *
98  * Revision 1.6 1999/09/01 19:04:54 lisa
99  * update Particle class AND add parity cf and Randys Coulomb correction
100  *
101  * Revision 1.5 1999/07/27 20:21:10 lisa
102  * Franks fixes of StTrack and subsequent changes to particleCut and EventReader
103  *
104  * Revision 1.4 1999/07/19 14:24:06 hardtke
105  * modifications to implement uDST
106  *
107  * Revision 1.3 1999/07/06 22:33:23 lisa
108  * Adjusted all to work in pro and new - dev itself is broken
109  *
110  * Revision 1.2 1999/06/29 17:50:27 fisyak
111  * formal changes to account new StEvent, does not complie yet
112  *
113  * Revision 1.1.1.1 1999/06/29 16:02:57 lisa
114  * Installation of StHbtMaker
