a4e98857 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).
990119d6 24// In addition it performs mixing of summable digits from different events.
7b7c1533 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
bca3b32a 29//
30// For each event two branches are created in TreeD:
31// "PHOS" - list of digits
32// "AliPHOSDigitizer" - AliPHOSDigitizer with all parameters used in digitization
33//
a4e98857 34// Note, that one can set a title for new digits branch, and repeat digitization with
bca3b32a 35// another set of parameters.
36//
a4e98857 37// Use case:
990119d6 38// root[0] AliPHOSDigitizer * d = new AliPHOSDigitizer() ;
39// root[1] d->ExecuteTask()
40// Warning in <TDatabasePDG::TDatabasePDG>: object already instantiated
41// //Digitizes SDigitis in all events found in file galice.root
bca3b32a 42//
8cb3533f 43// root[2] AliPHOSDigitizer * d1 = new AliPHOSDigitizer("galice1.root") ;
44// // Will read sdigits from galice1.root
45// root[3] d1->MixWith("galice2.root")
990119d6 46// Warning in <TDatabasePDG::TDatabasePDG>: object already instantiated
a4e98857 47// // Reads another set of sdigits from galice2.root
8cb3533f 48// root[3] d1->MixWith("galice3.root")
a4e98857 49// // Reads another set of sdigits from galice3.root
8cb3533f 50// root[4] d->ExecuteTask("deb timing")
51// // Reads SDigits from files galice1.root, galice2.root ....
52// // mixes them and stores produced Digits in file galice1.root
53// // deb - prints number of produced digits
54// // deb all - prints list of produced digits
55// // timing - prints time used for digitization
