19 | // This is a TTask that makes SDigits out of Hits | |
20 | // A Summable Digits is the sum of all hits originating | |
ffa6d63b | 21 | // from one in one tower of the EMCAL |
61e0abb5 | 22 | // A threshold for assignment of the primary to SDigit is applied |
23 | // SDigits are written to TreeS, branch "EMCAL" | |
24 | // AliEMCALSDigitizer with all current parameters is written | |
25 | // to TreeS branch "AliEMCALSDigitizer". | |
26 | // Both branches have the same title. If necessary one can produce | |
27 | // another set of SDigits with different parameters. Two versions | |
28 | // can be distunguished using titles of the branches. | |
29 | // User case: | |
30 | // root [0] AliEMCALSDigitizer * s = new AliEMCALSDigitizer("galice.root") | |
31 | // Warning in <TDatabasePDG::TDatabasePDG>: object already instantiated | |
32 | // root [1] s->ExecuteTask() | |
33 | // // Makes SDigitis for all events stored in galice.root | |
34 | // root [2] s->SetPedestalParameter(0.001) | |
35 | // // One can change parameters of digitization | |
36 | // root [3] s->SetSDigitsBranch("Redestal 0.001") | |
37 | // // and write them into the new branch | |
38 | // root [4] s->ExeciteTask("deb all tim") | |
39 | // // available parameters: | |
40 | // deb - print # of produced SDigitis | |
41 | // deb all - print # and list of produced SDigits | |
42 | // tim - print benchmarking information | |
