a4e98857 | 86 | // This TTask performs digitization of Summable digits (in the PHOS case it is just |
87 | // the sum of contributions from all primary particles into a given cell). | |
990119d6 | 88 | // In addition it performs mixing of summable digits from different events. |
7b7c1533 | 89 | // The name of the TTask is also the title of the branch that will contain |
90 | // the created SDigits | |
91 | // The title of the TTAsk is the name of the file that contains the hits from | |
92 | // which the SDigits are created | |
bca3b32a | 93 | // |
94 | // For each event two branches are created in TreeD: | |
95 | // "PHOS" - list of digits | |
96 | // "AliPHOSDigitizer" - AliPHOSDigitizer with all parameters used in digitization | |
97 | // | |
a4e98857 | 98 | // Note, that one can set a title for new digits branch, and repeat digitization with |
bca3b32a | 99 | // another set of parameters. |
