34Applyed fixes to bugs found by Rene Brun. With many thanks. Some additonal
35bugs found by Rene require more work to fix. Will be fixed soon.
36
cd77595e 37Revision 1.13 2001/10/12 22:07:20 nilsen
38A patch for C++ io manipulation functions so that they will work both
39with GNU gcc 2.96 and GNU gcc 3.01 compilers. Needs to be tested with
40other platforms.
41
431a7819 42Revision 1.12 2001/08/24 21:06:37 nilsen
43Added more documentation, fixed up some coding violations, and some
44forward declorations.
45
85f1e34a 46Revision 1.11 2001/05/16 08:17:49 hristov
47Bug 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)
48
e99dbc71 49Revision 1.10 2001/02/09 00:00:57 nilsen
50Fixed compatibility problem with HP unix {ios::fmtflags -> Int_t}. Fixed
51bugs in iostream based streamers used to read and write .det files. Fixed
52some detector sizes. Fixed bugs in some default-special constructors.
53
31b8cd63 54Revision 1.9 2001/02/03 00:00:30 nilsen
55New version of AliITSgeom and related files. Now uses automatic streamers,

85f1e34a 441Revision 1.11 2001/05/16 08:17:49 hristov
442Bug 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)
443
e99dbc71 444Revision 1.10 2001/02/09 00:00:57 nilsen
445Fixed compatibility problem with HP unix {ios::fmtflags -> Int_t}. Fixed
446bugs in iostream based streamers used to read and write .det files. Fixed
447some detector sizes. Fixed bugs in some default-special constructors.
448
31b8cd63 449Revision 1.9 2001/02/03 00:00:30 nilsen
450New version of AliITSgeom and related files. Now uses automatic streamers,
451set up for new formatted .det file which includes detector information.
452Additional smaller modifications are still to come.
