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. |
24 | // Examples of use: |
25 | // root[0] AliPHOSDigitizer * d = new AliPHOSDigitizer() ; |
26 | // root[1] d->ExecuteTask() |
27 | // Warning in <TDatabasePDG::TDatabasePDG>: object already instantiated |
28 | // //Digitizes SDigitis in all events found in file galice.root |
29 | // //Depending on variable "CONFIG_SPLIT_FILE" reads branches stored in galice.root |
30 | // //or in PHOS.SDigits.root |
8cb3533f |
31 | // root[2] AliPHOSDigitizer * d1 = new AliPHOSDigitizer("galice1.root") ; |
32 | // // Will read sdigits from galice1.root |
33 | // root[3] d1->MixWith("galice2.root") |
990119d6 |
34 | // Warning in <TDatabasePDG::TDatabasePDG>: object already instantiated |
8cb3533f |
35 | // // Reads another portion of sdigits from galice2.root |
36 | // root[3] d1->MixWith("galice3.root") |
37 | // // Reads another portion of sdigits from galice3.root |
38 | // root[4] d->ExecuteTask("deb timing") |
39 | // // Reads SDigits from files galice1.root, galice2.root .... |
40 | // // mixes them and stores produced Digits in file galice1.root |
41 | // // deb - prints number of produced digits |
42 | // // deb all - prints list of produced digits |
43 | // // timing - prints time used for digitization |
990119d6 |
