19 | Corrected by F. Carminati for v3.04 | |
20 | ||
114da3a4 | 21 | Revision 1.8 2000/10/02 16:32:57 barbera |
22 | Forward declarations added and formatting | |
23 | ||
0b2d41b4 | 24 | Revision 1.3.4.8 2000/10/02 15:55:26 barbera |
25 | Forward declarations added and formatting | |
26 | ||
27 | Revision 1.7 2000/09/22 12:36:38 nilsen | |
28 | Minor changes to improve compilation and create less NOISE. | |
29 | ||
ff61221e | 30 | Revision 1.6 2000/07/10 16:07:18 fca |
31 | Release version of ITS code | |
32 | ||
3bd79107 | 33 | Revision 1.3.4.2 2000/03/02 21:42:29 nilsen |
34 | Linked AliDetector::fDigit to AliITSmodule::fDigitsM and AliITS::fITSRecPoints | |
35 | to AliITSmodule::fRecPointsM. Renamed AliITSmodule::fPointsM to fRecPointsM. | |
36 | Removed the deletion of fDigitsM from the distructor since it is only a copy | |
37 | of what is in AliDetector. Fixed a bug in the functions LineSegmentL and | |
38 | LineSegmentG. Added two new versions of LineSegmentL and LineSegmentG to | |
39 | additionaly return track number from the hit. Removed FastPoint function, | |
40 | haven't found anywere it was used, also it had very many problems, should | |
41 | just call FastPointSPD... . | |
42 | ||
43 | Revision 1.3.4.1 2000/01/12 19:03:32 nilsen | |
44 | This is the version of the files after the merging done in December 1999. | |
45 | See the ReadMe110100.txt file for details | |
46 | ||
47 | Revision 1.3 1999/10/04 15:20:12 fca | |
48 | Correct syntax accepted by g++ but not standard for static members, remove minor warnings | |
