28//// AliTPCMonitorAltro class
29////
30//// Class for decoding raw TPC data in the ALTRO format.
31//// Data are transformed from 32 bit words to 10 bit or 40 bit respectively.
32//// The whole payload is transformed at once and written to an array.
33//// The single channels are decoded starting from the trailer word which is
34//// decoded by DecodeTrailer(Int_t pos)
35////
