a4e98857 | 21 | // This TTask performs digitization of Summable digits (in the PHOS case it is just |
22 | // the sum of contributions from all primary particles into a given cell). | |
990119d6 | 23 | // In addition it performs mixing of summable digits from different events. |
7b7c1533 | 24 | // The name of the TTask is also the title of the branch that will contain |
25 | // the created SDigits | |
26 | // The title of the TTAsk is the name of the file that contains the hits from | |
27 | // which the SDigits are created | |
bca3b32a | 28 | // |
29 | // For each event two branches are created in TreeD: | |
30 | // "PHOS" - list of digits | |
31 | // "AliPHOSDigitizer" - AliPHOSDigitizer with all parameters used in digitization | |
32 | // | |
a4e98857 | 33 | // Note, that one can set a title for new digits branch, and repeat digitization with |
bca3b32a | 34 | // another set of parameters. |
35 | // | |

990119d6 | 37 | // root[0] AliPHOSDigitizer * d = new AliPHOSDigitizer() ; |

39 | // Warning in <TDatabasePDG::TDatabasePDG>: object already instantiated | |
40 | // //Digitizes SDigitis in all events found in file galice.root | |
