65fb704d | 18 | Revision 1.24 2000/10/18 19:11:27 hristov |
19 | Division by zero fixed | |
20 | ||
919c2096 | 21 | Revision 1.23 2000/10/02 21:28:06 fca |
22 | Removal of useless dependecies via forward declarations | |
23 | ||
94de3818 | 24 | Revision 1.22 2000/09/12 14:14:55 morsch |
25 | Call fDecayer->ForceDecay() at the beginning of Generate(). | |
26 | ||
00d6ce7d | 27 | Revision 1.21 2000/09/08 15:39:01 morsch |
28 | Handle the case fForceDecay=all during the generation, i.e. select all secondaries. | |
29 | ||
5ab0acc9 | 30 | Revision 1.20 2000/09/06 14:35:44 morsch |
31 | Use AliDecayerPythia for particle decays. | |
32 | ||
fa480368 | 33 | Revision 1.19 2000/07/11 18:24:56 fca |
34 | Coding convention corrections + few minor bug fixes | |
35 | ||
aee8290b | 36 | Revision 1.18 2000/06/29 21:08:27 morsch |
37 | All paramatrisation libraries derive from the pure virtual base class AliGenLib. | |
38 | This allows to pass a pointer to a library directly to AliGenParam and avoids the | |
39 | use of function pointers in Config.C. | |
40 | ||
b22ee262 | 41 | Revision 1.17 2000/06/09 20:33:30 morsch |
42 | All coding rule violations except RS3 corrected | |
43 | ||
f87cfe57 | 44 | Revision 1.16 2000/05/02 07:51:31 morsch |
45 | - Control precision of pT sampling TF1::SetNpx(..) | |
46 | - Correct initialisation of child-cuts in all constructors. | |
47 | - Most coding rule violations corrected. | |
48 | ||
749070b6 | 49 | Revision 1.15 2000/04/03 15:42:12 morsch |
50 | Cuts on primary particles are separated from those on the decay products. Methods | |
51 | SetChildMomentumRange, SetChildPtRange, SetChildPhiRange, SetChildThetaRange added. | |
52 | ||
cc5d764c | 53 | Revision 1.14 1999/11/09 07:38:48 fca |
54 | Changes for compatibility with version 2.23 of ROOT | |
55 | ||
084c1b4a | 56 | Revision 1.13 1999/11/04 11:30:31 fca |
57 | Correct the logics for SetForceDecay | |
58 | ||
28337bc1 | 59 | Revision 1.12 1999/11/03 17:43:20 fca |
60 | New version from G.Martinez & A.Morsch | |
