94831058 18Revision 1.14 2001/11/19 16:17:03 nilsen
19Applyed fixes to bugs found by Rene Brun. With many thanks. Some additonal
20bugs found by Rene require more work to fix. Will be fixed soon.
21
cd77595e 22Revision 1.13 2001/10/12 22:07:20 nilsen
23A patch for C++ io manipulation functions so that they will work both
24with GNU gcc 2.96 and GNU gcc 3.01 compilers. Needs to be tested with
25other platforms.
26
431a7819 27Revision 1.12 2001/08/24 21:06:37 nilsen
28Added more documentation, fixed up some coding violations, and some
29forward declorations.
30
85f1e34a 31Revision 1.11 2001/05/16 08:17:49 hristov
32Bug 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)
33
e99dbc71 34Revision 1.10 2001/02/09 00:00:57 nilsen
35Fixed compatibility problem with HP unix {ios::fmtflags -> Int_t}. Fixed
36bugs in iostream based streamers used to read and write .det files. Fixed
37some detector sizes. Fixed bugs in some default-special constructors.
38
31b8cd63 39Revision 1.9 2001/02/03 00:00:30 nilsen
40New version of AliITSgeom and related files. Now uses automatic streamers,
41set up for new formatted .det file which includes detector information.
42Additional smaller modifications are still to come.

94831058 477Revision 1.14 2001/11/19 16:17:03 nilsen
478Applyed fixes to bugs found by Rene Brun. With many thanks. Some additonal
479bugs found by Rene require more work to fix. Will be fixed soon.
480
cd77595e 481Revision 1.13 2001/10/12 22:07:20 nilsen
482A patch for C++ io manipulation functions so that they will work both
483with GNU gcc 2.96 and GNU gcc 3.01 compilers. Needs to be tested with
484other platforms.
485
431a7819 486Revision 1.12 2001/08/24 21:06:37 nilsen
487Added more documentation, fixed up some coding violations, and some
488forward declorations.
489
85f1e34a 490Revision 1.11 2001/05/16 08:17:49 hristov
491Bug 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)
492
e99dbc71 493Revision 1.10 2001/02/09 00:00:57 nilsen
494Fixed compatibility problem with HP unix {ios::fmtflags -> Int_t}. Fixed
495bugs in iostream based streamers used to read and write .det files. Fixed
496some detector sizes. Fixed bugs in some default-special constructors.
497
31b8cd63 498Revision 1.9 2001/02/03 00:00:30 nilsen
499New version of AliITSgeom and related files. Now uses automatic streamers,
500set up for new formatted .det file which includes detector information.
501Additional smaller modifications are still to come.
