34 | Fixed bug with non-zero-ed new data members in constructors. Thanks Jiri | |

07265b7c | 37 | Revision 1.15 2002/06/12 18:59:47 nilsen |
38 | Added Starting track location to hit class and related changes to modules. | |
39 | This is at present still fully backwards compatible since starting hits | |
40 | are still written to the file. When aliroot v4.0 will be released, this | |
41 | backwards compatiblity will be broken by removing the enterence hit, and making | |
42 | the nessesary changes to module at that time. | |
