a4e98857 35// This TTask performs digitization of Summable digits (in the PHOS case it is just
36// the sum of contributions from all primary particles into a given cell).
990119d6 37// In addition it performs mixing of summable digits from different events.
7b7c1533 38// The name of the TTask is also the title of the branch that will contain
39// the created SDigits
40// The title of the TTAsk is the name of the file that contains the hits from
41// which the SDigits are created
bca3b32a 42//
43// For each event two branches are created in TreeD:
44// "PHOS" - list of digits
45// "AliPHOSDigitizer" - AliPHOSDigitizer with all parameters used in digitization
46//
a4e98857 47// Note, that one can set a title for new digits branch, and repeat digitization with
bca3b32a 48// another set of parameters.
49//
a4e98857 50// Use case:
990119d6 51// root[0] AliPHOSDigitizer * d = new AliPHOSDigitizer() ;
52// root[1] d->ExecuteTask()
53// Warning in <TDatabasePDG::TDatabasePDG>: object already instantiated
54// //Digitizes SDigitis in all events found in file galice.root
bca3b32a 55//
8cb3533f 56// root[2] AliPHOSDigitizer * d1 = new AliPHOSDigitizer("galice1.root") ;
57// // Will read sdigits from galice1.root
58// root[3] d1->MixWith("galice2.root")
990119d6 59// Warning in <TDatabasePDG::TDatabasePDG>: object already instantiated
a4e98857 60// // Reads another set of sdigits from galice2.root
8cb3533f 61// root[3] d1->MixWith("galice3.root")
a4e98857 62// // Reads another set of sdigits from galice3.root
8cb3533f 63// root[4] d->ExecuteTask("deb timing")
64// // Reads SDigits from files galice1.root, galice2.root ....
65// // mixes them and stores produced Digits in file galice1.root
66// // deb - prints number of produced digits
67// // deb all - prints list of produced digits
68// // timing - prints time used for digitization
