19Merging the VirtualMC branch to the main development branch (HEAD)
20
b9d0a01d 21Revision 1.14.6.1 2002/06/10 17:51:15 hristov
22Merged with v3-08-02
23
24Revision 1.15 2002/05/19 18:17:03 hristov
25Changes needed by ICC/IFC compiler (Intel)
26
94831058 27Revision 1.14 2001/11/19 16:17:03 nilsen
28Applyed fixes to bugs found by Rene Brun. With many thanks. Some additonal
29bugs found by Rene require more work to fix. Will be fixed soon.
30
cd77595e 31Revision 1.13 2001/10/12 22:07:20 nilsen
32A patch for C++ io manipulation functions so that they will work both
33with GNU gcc 2.96 and GNU gcc 3.01 compilers. Needs to be tested with
34other platforms.
35
431a7819 36Revision 1.12 2001/08/24 21:06:37 nilsen
37Added more documentation, fixed up some coding violations, and some
38forward declorations.
39
85f1e34a 40Revision 1.11 2001/05/16 08:17:49 hristov
41Bug fixed in the StepManager to account for the difference in the geometry tree for the ITS pixels. This fixes both the funny distribution of pixel coordinates and the missing hits/digits/points in many sectors of the ITS pixel barrel. Also included is a patch to properly get and use the detector dimensions through out the ITS code. (B.Nilsen)
42
e99dbc71 43Revision 1.10 2001/02/09 00:00:57 nilsen
44Fixed compatibility problem with HP unix {ios::fmtflags -> Int_t}. Fixed
45bugs in iostream based streamers used to read and write .det files. Fixed
46some detector sizes. Fixed bugs in some default-special constructors.
47
31b8cd63 48Revision 1.9 2001/02/03 00:00:30 nilsen
49New version of AliITSgeom and related files. Now uses automatic streamers,
50set up for new formatted .det file which includes detector information.
51Additional smaller modifications are still to come.

4ae5bbc4 503Revision 1.16 2002/10/14 14:57:00 hristov
504Merging the VirtualMC branch to the main development branch (HEAD)
505
b9d0a01d 506Revision 1.14.6.1 2002/06/10 17:51:15 hristov
507Merged with v3-08-02
508
509Revision 1.15 2002/05/19 18:17:03 hristov
510Changes needed by ICC/IFC compiler (Intel)
511
94831058 512Revision 1.14 2001/11/19 16:17:03 nilsen
513Applyed fixes to bugs found by Rene Brun. With many thanks. Some additonal
514bugs found by Rene require more work to fix. Will be fixed soon.
515
cd77595e 516Revision 1.13 2001/10/12 22:07:20 nilsen
517A patch for C++ io manipulation functions so that they will work both
518with GNU gcc 2.96 and GNU gcc 3.01 compilers. Needs to be tested with
519other platforms.
520
431a7819 521Revision 1.12 2001/08/24 21:06:37 nilsen
522Added more documentation, fixed up some coding violations, and some
523forward declorations.
524
85f1e34a 525Revision 1.11 2001/05/16 08:17:49 hristov
526Bug fixed in the StepManager to account for the difference in the geometry tree for the ITS pixels. This fixes both the funny distribution of pixel coordinates and the missing hits/digits/points in many sectors of the ITS pixel barrel. Also included is a patch to properly get and use the detector dimensions through out the ITS code. (B.Nilsen)
527
e99dbc71 528Revision 1.10 2001/02/09 00:00:57 nilsen
529Fixed compatibility problem with HP unix {ios::fmtflags -> Int_t}. Fixed
530bugs in iostream based streamers used to read and write .det files. Fixed
531some detector sizes. Fixed bugs in some default-special constructors.
532
31b8cd63 533Revision 1.9 2001/02/03 00:00:30 nilsen
534New version of AliITSgeom and related files. Now uses automatic streamers,
535set up for new formatted .det file which includes detector information.
536Additional smaller modifications are still to come.
