17 | // Task Class for making SDigits in PHOS | |
18 | // Class performs digitization of Summable digits (in the PHOS case this is just | |
19 | // sum of contributions of all primary particles into given cell). | |
20 | // In addition it performs mixing of summable digits from different events. | |
