86 // This class 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).
88 // In addition it performs mixing of summable digits from different events.

90 // the created SDigits
91 // The title of the class is the name of the file that contains the hits from
92 // which the SDigits are created
94 // For each event two branches are created in TreeD:
95 // "PHOS" - list of digits
96 // "AliPHOSDigitizer" - AliPHOSDigitizer with all parameters used in digitization
98 // Note, that one can set a title for new digits branch, and repeat digitization with
99 // another set of parameters.
