10 | // creates sdigits for several detectors | |
11 | // stores sdigits in separate file (or in the source file | |
12 | // with hits). Stores gAlice object and copies TE to the | |
13 | // file with sdigits | |
14 | // | |
15 | // input: | |
16 | // TString fileNameSDigits ... output file with sdigits | |
17 | // TString fileNameHits ... input file with hits | |
18 | // Int_t nEvents ... how many events to proceed | |
19 | // Int_t firstEvent ... first event number | |
20 | // Int_t ITS, TPC, ... many flags for diff. detectors | |
21 | // | |
22 | // History: | |
23 | // | |
24 | // 04.04.02 - first version | |
