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