The channel mapping is used to bring the channels in the right order for the 2D-projections. Since the mapping may change from time to time, every run is assigned to a specific channel mapping. Below is the structure of the database table:
Date corresponds to the time when this channel mapping has been applied. CH0 - CH29 are the channels for the X-Z projection, CH30 - CH60 are the channels for the Y-Z projection. The numbers in the fields are the corresponding VME channels. For building the 2D projections the method GetChannelMapping() in the Run_t class is called which returns an array of size 62 where the index corresponds to the projection channel and the value to the VME channel.
