a30a000f | 18 | Revision 1.5 2000/06/29 12:34:09 morsch |
19 | AliMUONSegmentation class has been made independent of AliMUONChamber. This makes | |
20 | it usable with any other geometry class. The link to the object to which it belongs is | |
21 | established via an index. This assumes that there exists a global geometry manager | |
22 | from which the pointer to the parent object can be obtained (in our case gAlice). | |

d81db581 | 24 | Revision 1.4 2000/06/29 06:52:02 pcrochet |
25 | pow changed to TMath::Power | |
26 | ||
39f5a0e6 | 27 | Revision 1.3 2000/06/28 15:16:35 morsch |
28 | (1) Client code adapted to new method signatures in AliMUONSegmentation (see comments there) | |
29 | to allow development of slat-muon chamber simulation and reconstruction code in the MUON | |
30 | framework. The changes should have no side effects (mostly dummy arguments). | |
31 | (2) Hit disintegration uses 3-dim hit coordinates to allow simulation | |
32 | of chambers with overlapping modules (MakePadHits, Disintegration). | |
33 | ||
802a864d | 34 | Revision 1.2 2000/06/15 07:58:48 morsch |
35 | Code from MUON-dev joined | |
36 | ||
a9e2aefa | 37 | Revision 1.1.2.3 2000/06/09 21:27:35 morsch |
38 | Most coding rule violations corrected. | |
39 | ||
40 | Revision 1.1.2.2 2000/04/26 12:28:25 morsch | |
41 | - flag pad hits with condition on ToF (CP) | |
42 | - Tof included in the method DisIntegration (CP) | |
