19 | Bug fix. | |
20 | ||
2d408567 | 21 | Revision 1.9 2001/02/09 00:00:57 nilsen |
22 | Fixed compatibility problem with HP unix {ios::fmtflags -> Int_t}. Fixed | |
23 | bugs in iostream based streamers used to read and write .det files. Fixed | |
24 | some detector sizes. Fixed bugs in some default-special constructors. | |
25 | ||
31b8cd63 | 26 | Revision 1.8 2001/02/03 00:00:30 nilsen |
27 | New version of AliITSgeom and related files. Now uses automatic streamers, | |
28 | set up for new formatted .det file which includes detector information. | |
29 | Additional smaller modifications are still to come. | |

e99dbc71 | 445 | Revision 1.10 2001/04/26 22:44:34 nilsen |
446 | Bug fix. | |
447 | ||
2d408567 | 448 | Revision 1.9 2001/02/09 00:00:57 nilsen |
449 | Fixed compatibility problem with HP unix {ios::fmtflags -> Int_t}. Fixed | |
450 | bugs in iostream based streamers used to read and write .det files. Fixed | |
451 | some detector sizes. Fixed bugs in some default-special constructors. | |
452 | ||
31b8cd63 | 453 | Revision 1.8 2001/02/03 00:00:30 nilsen |
454 | New version of AliITSgeom and related files. Now uses automatic streamers, | |
455 | set up for new formatted .det file which includes detector information. | |
456 | Additional smaller modifications are still to come. | |
