19 // AliTOFDigitMap class
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.
