7b7c1533 | 29 | // The name of the TTask is also the title of the branch that will contain |
30 | // the created SDigits | |
31 | // The title of the TTAsk is the name of the file that contains the hits from | |
32 | // which the SDigits are created | |
7acf6008 | 33 | // A Summable Digits is the sum of all hits originating |
34 | // from one primary in one active cell | |
35 | // A threshold for assignment of the primary to SDigit is applied | |
36 | // SDigits are written to TreeS, branch "PHOS" | |
37 | // AliPHOSSDigitizer with all current parameters is written | |
38 | // to TreeS branch "AliPHOSSDigitizer". | |
f035f6ce | 39 | // Both branches have the same title. If necessary one can produce |
40 | // another set of SDigits with different parameters. Two versions | |
41 | // can be distunguished using titles of the branches. | |

44 | // Warning in <TDatabasePDG::TDatabasePDG>: object already instantiated | |
