a4e98857 | 32 | // This TTask performs digitization of Summable digits (in the PHOS case it is just |
33 | // the sum of contributions from all primary particles into a given cell). | |
990119d6 | 34 | // In addition it performs mixing of summable digits from different events. |
7b7c1533 | 35 | // The name of the TTask is also the title of the branch that will contain |
36 | // the created SDigits | |
37 | // The title of the TTAsk is the name of the file that contains the hits from | |
38 | // which the SDigits are created | |
bca3b32a | 39 | // |
40 | // For each event two branches are created in TreeD: | |
41 | // "PHOS" - list of digits | |
42 | // "AliPHOSDigitizer" - AliPHOSDigitizer with all parameters used in digitization | |
43 | // | |
a4e98857 | 44 | // Note, that one can set a title for new digits branch, and repeat digitization with |
bca3b32a | 45 | // another set of parameters. |
46 | // | |
a4e98857 | 47 | // Use case: |
990119d6 | 48 | // root[0] AliPHOSDigitizer * d = new AliPHOSDigitizer() ; |
49 | // root[1] d->ExecuteTask() | |
50 | // Warning in <TDatabasePDG::TDatabasePDG>: object already instantiated | |
51 | // //Digitizes SDigitis in all events found in file galice.root | |
bca3b32a | 52 | // |
8cb3533f | 53 | // root[2] AliPHOSDigitizer * d1 = new AliPHOSDigitizer("galice1.root") ; |
54 | // // Will read sdigits from galice1.root | |
55 | // root[3] d1->MixWith("galice2.root") | |
990119d6 | 56 | // Warning in <TDatabasePDG::TDatabasePDG>: object already instantiated |
a4e98857 | 57 | // // Reads another set of sdigits from galice2.root |
8cb3533f | 58 | // root[3] d1->MixWith("galice3.root") |
a4e98857 | 59 | // // Reads another set of sdigits from galice3.root |
8cb3533f | 60 | // root[4] d->ExecuteTask("deb timing") |
61 | // // Reads SDigits from files galice1.root, galice2.root .... | |
62 | // // mixes them and stores produced Digits in file galice1.root | |
63 | // // deb - prints number of produced digits | |
