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