86 | // This class performs digitization of Summable digits (in the PHOS case it is just | |
87 | // the sum of contributions from all primary particles into a given cell). | |
88 | // In addition it performs mixing of summable digits from different events. | |
89 | // The name of the class is also the title of the branch that will contain | |
90 | // the created SDigits | |
91 | // The title of the class is the name of the file that contains the hits from | |
92 | // which the SDigits are created | |
93 | // | |
94 | // For each event two branches are created in TreeD: | |
95 | // "PHOS" - list of digits | |
96 | // "AliPHOSDigitizer" - AliPHOSDigitizer with all parameters used in digitization | |
97 | // | |
98 | // Note, that one can set a title for new digits branch, and repeat digitization with | |
99 | // another set of parameters. | |
100 | // | |
101 | // Use case: | |
102 | // root[0] AliPHOSDigitizer * d = new AliPHOSDigitizer() ; | |
103 | // root[1] d->Digitize() | |
104 | // Warning in <TDatabasePDG::TDatabasePDG>: object already instantiated | |
105 | // //Digitizes SDigitis in all events found in file galice.root | |
106 | // | |
107 | // root[2] AliPHOSDigitizer * d1 = new AliPHOSDigitizer("galice1.root") ; | |
108 | // // Will read sdigits from galice1.root | |
109 | // root[3] d1->MixWith("galice2.root") | |
110 | // Warning in <TDatabasePDG::TDatabasePDG>: object already instantiated | |
111 | // // Reads another set of sdigits from galice2.root | |
112 | // root[3] d1->MixWith("galice3.root") | |
113 | // // Reads another set of sdigits from galice3.root | |
114 | // root[4] d->Digitize("deb timing") | |
115 | // // Reads SDigits from files galice1.root, galice2.root .... | |
116 | // // mixes them and stores produced Digits in file galice1.root | |
117 | // // deb - prints number of produced digits | |
118 | // // deb all - prints list of produced digits | |
119 | // // timing - prints time used for digitization | |
