ecfa008b | 18 | Revision 1.6 2000/07/03 11:54:57 morsch |
19 | AliMUONSegmentation and AliMUONHitMap have been replaced by AliSegmentation and AliHitMap in STEER | |
20 | The methods GetPadIxy and GetPadXxy of AliMUONSegmentation have changed name to GetPadI and GetPadC. | |
21 | ||
a30a000f | 22 | Revision 1.5 2000/06/29 12:34:09 morsch |
23 | AliMUONSegmentation class has been made independent of AliMUONChamber. This makes | |
24 | it usable with any other geometry class. The link to the object to which it belongs is | |
25 | established via an index. This assumes that there exists a global geometry manager | |
26 | from which the pointer to the parent object can be obtained (in our case gAlice). | |
27 | ||
d81db581 | 28 | Revision 1.4 2000/06/29 06:52:02 pcrochet |
29 | pow changed to TMath::Power | |
30 | ||
39f5a0e6 | 31 | Revision 1.3 2000/06/28 15:16:35 morsch |
32 | (1) Client code adapted to new method signatures in AliMUONSegmentation (see comments there) | |
33 | to allow development of slat-muon chamber simulation and reconstruction code in the MUON | |
34 | framework. The changes should have no side effects (mostly dummy arguments). | |
35 | (2) Hit disintegration uses 3-dim hit coordinates to allow simulation | |
36 | of chambers with overlapping modules (MakePadHits, Disintegration). | |
37 | ||
802a864d | 38 | Revision 1.2 2000/06/15 07:58:48 morsch |
39 | Code from MUON-dev joined | |
40 | ||
a9e2aefa | 41 | Revision 1.1.2.3 2000/06/09 21:27:35 morsch |
42 | Most coding rule violations corrected. | |
43 | ||
44 | Revision 1.1.2.2 2000/04/26 12:28:25 morsch | |
45 | - flag pad hits with condition on ToF (CP) | |
46 | - Tof included in the method DisIntegration (CP) | |
