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