8/// This is a class for reading the VZERO DDL raw data
9/// The format of the raw data corresponds to the one
10/// implemented in AliVZEROBuffer class.
11///
1ecef4c5 12/// PLEASE NOTE that Int_t channel is here the FEE channel from 0 to 63 in the
13/// order defined by Yannick Zoccarato which is not the same order as the order
14/// defined in aliroot by the naming and numbering conventions.
15/// Therefore one has to go from FEE_Channel to AliRoot_Channel using
16/// GetOfflineChannel(Int_t channel) when going from Online to Offline !!!
