22 // the sum of contributions from all primary particles into a given cell).
23 // In addition it performs mixing of summable digits from different events.

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
29 // For each event two branches are created in TreeD:
30 // "PHOS" - list of digits
31 // "AliPHOSDigitizer" - AliPHOSDigitizer with all parameters used in digitization
33 // Note, that one can set a title for new digits branch, and repeat digitization with
34 // another set of parameters.
