a4e98857 21// This TTask performs digitization of Summable digits (in the PHOS case it is just
22// the sum of contributions from all primary particles into a given cell).
990119d6 23// In addition it performs mixing of summable digits from different events.
7b7c1533 24// The name of the TTask is also the title of the branch that will contain
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
bca3b32a 28//
29// For each event two branches are created in TreeD:
30// "PHOS" - list of digits
31// "AliPHOSDigitizer" - AliPHOSDigitizer with all parameters used in digitization
32//
a4e98857 33// Note, that one can set a title for new digits branch, and repeat digitization with
bca3b32a 34// another set of parameters.
35//
a4e98857 36// Use case:
990119d6 37// root[0] AliPHOSDigitizer * d = new AliPHOSDigitizer() ;
38// root[1] d->ExecuteTask()
39// Warning in <TDatabasePDG::TDatabasePDG>: object already instantiated
40// //Digitizes SDigitis in all events found in file galice.root
bca3b32a 41//
8cb3533f 42// root[2] AliPHOSDigitizer * d1 = new AliPHOSDigitizer("galice1.root") ;
43// // Will read sdigits from galice1.root
44// root[3] d1->MixWith("galice2.root")
990119d6 45// Warning in <TDatabasePDG::TDatabasePDG>: object already instantiated
a4e98857 46// // Reads another set of sdigits from galice2.root
8cb3533f 47// root[3] d1->MixWith("galice3.root")
a4e98857 48// // Reads another set of sdigits from galice3.root
8cb3533f 49// root[4] d->ExecuteTask("deb timing")
50// // Reads SDigits from files galice1.root, galice2.root ....
51// // mixes them and stores produced Digits in file galice1.root
52// // deb - prints number of produced digits
53// // deb all - prints list of produced digits
54// // timing - prints time used for digitization
