19 | Include Slat chambers (stations 3-5) into geometry (A. de Falco) | |
20 | ||
1e8fff9c | 21 | Revision 1.7 2000/10/02 21:28:09 fca |
22 | Removal of useless dependecies via forward declarations | |
23 | ||
94de3818 | 24 | Revision 1.6 2000/10/02 17:20:45 egangler |
25 | Cleaning of the code (continued ) : | |
26 | -> coding conventions | |
27 | -> void Streamers | |
28 | -> some useless includes removed or replaced by "class" statement | |

8c449e83 | 30 | Revision 1.5 2000/06/28 15:16:35 morsch |
31 | (1) Client code adapted to new method signatures in AliMUONSegmentation (see comments there) | |
32 | to allow development of slat-muon chamber simulation and reconstruction code in the MUON | |
33 | framework. The changes should have no side effects (mostly dummy arguments). | |
34 | (2) Hit disintegration uses 3-dim hit coordinates to allow simulation | |
35 | of chambers with overlapping modules (MakePadHits, Disintegration). | |
36 | ||
802a864d | 37 | Revision 1.4 2000/06/26 14:02:38 morsch |
38 | Add class AliMUONConstants with MUON specific constants using static memeber data and access methods. | |
