7acf6008 | 31 | // This is a TTask that makes SDigits out of Hits |
7b7c1533 | 32 | // The name of the TTask is also the title of the branch that will contain |
33 | // the created SDigits | |
34 | // The title of the TTAsk is the name of the file that contains the hits from | |
35 | // which the SDigits are created | |
7acf6008 | 36 | // A Summable Digits is the sum of all hits originating |
37 | // from one primary in one active cell | |
38 | // A threshold for assignment of the primary to SDigit is applied | |
39 | // SDigits are written to TreeS, branch "PHOS" | |
40 | // AliPHOSSDigitizer with all current parameters is written | |
41 | // to TreeS branch "AliPHOSSDigitizer". | |
f035f6ce | 42 | // Both branches have the same title. If necessary one can produce |
43 | // another set of SDigits with different parameters. Two versions | |
44 | // can be distunguished using titles of the branches. | |

a4e98857 | 46 | // root [0] AliPHOSSDigitizer * s = new AliPHOSSDigitizer("galice.root") |
47 | // Warning in <TDatabasePDG::TDatabasePDG>: object already instantiated | |

3de072dc | 52 | // root [3] s->SetSDigitsBranch("Pedestal 0.001") |
f035f6ce | 53 | // // and write them into the new branch |
