2 // $Log: StFtpcConfMapPoint.hh,v $
3 // Revision 1.5 2004/04/06 18:36:13 oldi
4 // New data mebers for pad and time position and pad and time sigma added.
5 // Reference to StFtpcHit added.
6 // Possibility to update StFtpcHit coordinates directly included.
7 //
8 // Revision 1.4 2004/02/12 19:37:09 oldi
9 // *** empty log message ***
10 //
11 // Revision 1.3 2000/11/10 18:34:31 oldi
12 // New constructor added.
13 //
14 // Revision 1.2 2000/07/18 21:22:15 oldi
15 // Changes due to be able to find laser tracks.
16 // Cleanup: - new functions in StFtpcConfMapper, StFtpcTrack, and StFtpcPoint
17 // to bundle often called functions
18 // - short functions inlined
19 // - formulas of StFormulary made static
20 // - avoid streaming of objects of unknown size
21 // (removes the bunch of CINT warnings during compile time)
22 // - two or three minor bugs cured
23 //
24 // Revision 1.1 2000/05/11 15:14:40 oldi
25 // Changed class names *Hit.* due to already existing class StFtpcHit.cxx in StEvent
26 //
27 
29 // //
30 // StFtpcConfMapPoint class - derived FTPC Hit class to represent additional data //
31 // needed by the conformel mapping track algorithm. //
