19 | // AliTOFDigitMap class | |
20 | // | |
21 | // digitmap enables fast check if the pad was already hit | |
22 | // The index of a AliTOFdigit is saved in the each hitmap "cell" | |
23 | // (there is an offset +1, because the index can be zero and | |
24 | // zero means empty cell. | |
25 | // In TOF, number of strips varies according plate type, the highest | |
26 | // number is in plate C. For all plates is used this number, so | |
27 | // the size of the digitmap is a little bit greater than necessary, but | |
28 | // it simplifies the access algorithm. | |
