40Bug fix in the creation of the AliITSgeom::fShape entry for SPD. Now there is both a proper shape entry and a default, should there be future changes. This bug was related to fMinorVersion=3 was not antisipated. (B.Nilsen)
41
3e225ff6 42Revision 1.14 2001/05/16 14:57:16 alibrary
43New files for folders and Stack
44
9e1a0ddb 45Revision 1.13 2001/05/09 01:00:19 nilsen
46Fixed up a typo in the cout of Init(). Now properly indecates which version
47of code is being used.
48
82140a73 49Revision 1.12 2001/04/18 12:06:02 barbera
50Number of modules in layer 5 and 6 re-set to 23 and 26
51
18c21458 52Revision 1.11 2001/03/23 00:12:23 nilsen
53Set Reading of AliITSgeom data from Geant3 common blocks as the default and
54not a .det file. Removed redundent calls to BuildGeometry.
55
0646a0e8 56Revision 1.10 2001/02/14 14:22:58 nilsen
57Now looking in the right director for the old .det.
58
202679a1 59Revision 1.9 2001/02/14 14:12:43 nilsen
60Forgot about the nonexisting v in ITSgeometry_5.det.
61
262d891d 62Revision 1.8 2001/02/14 14:06:23 nilsen
63Wrong default .det file name for old .det file format.
64
88cc8e8a 65Revision 1.7 2001/02/13 16:53:35 nilsen
66Fixed a but when trying to use GEANT4. Needed to replace
67if(!((TGeant3*)gMC)) with if(!(dynamic_casst<TGeant3*>(gMC)))
68because just casting gMC to be TGeant3* even when it realy is a TGeant3 pointer
69did not result in a zero value. For AliITSv5asymm and AliITSv5symm, needed
70to fix a bug in the initilizers and a bug in BuildGeometry. This is now done
71in the same way as in AliITSv5.cxx.
72
9a4c6ea3 73Revision 1.6 2001/02/09 20:06:26 nilsen
