Table lists the group suffixes recognised by the display system. In a similar way to frame definitions, all group id's are prefixed by `gN' where `g' indicates that a group is being displayed and `N' is the sub-instrument number. Unlike for frames, the gN prefix is always attached regardless of the number of sub-instruments in the group.
The _REBIN_EM2_GROUP_ primitive uses a gNpa-thr where `pa' refers to the position angle of the chopped data and `thr' to the chop throw. For example, to view the rebinned image of the data taken with 65 arcsec chop at 90 degrees position angle for the first sub-instrument a display id of `g190-65' would be required.
