Identifies which channels (1,2,3,4) of IFU data are contained in an exposure. For exposures on the MIRIFUSHORT detector, CHANNEL will indicate that data from both channels 1 and 2 are present with a value of '12'. Similarly, for the MIRIFULONG detector, CHANNEL will be '34' to indicate that data from channels 3 and 4 are present.
