24////
25//// AliTPCMonitorAltro class
26////
27//// Class for decoding raw TPC data in the ALTRO format.
28//// Data are transformed from 32 bit words to 10 bit or 40 bit respectively.
29//// The whole payload is transformed at once and written to an array.
30//// The single channels are decoded starting from the trailer word which is
31//// decoded by DecodeTrailer(Int_t pos)
32////
33//// Authors: Roland Bramm,
34//// Stefan Kniege, IKF, Frankfurt
