Displaying frame output

For SCUBA data, the products of early stages of data reduction (e.g. flatfielding or despiking) are not really suitable for display so many of the early primitives do not contain display directives.

Table lists the suffices along with the primitives that generate the display request (and therefore must be called in the recipe).

Table: Suffix values used to display individual frames

Suffix	Type of image	Primitives
noise	Noise	_REDUCE_NOISE_
sdip	Skydip	_DISPLAY_SKYDIP_
pht	Photometrt data	_DISPLAY_PHOTOM_GROUP_
reb	Rebinned image	_REBIN_FRAME_
pol	Polarisation (I,P,THETA) image	_CALCULATE_POLARISATION_FRAME_
p	Polarisation P image	_CALCULATE_POLARISATION_FRAME_
theta	Polarisation THETA image	_CALCULATE_POLARISATION_FRAME_

Each of these suffixes can be prefixed by an `sN' prefix where `s' stands for sub-instrument and N is a number indicating the position of the sub-instrument in the raw data (for SCUBA N is usefully between 1 and 3). For example, a display definition to display both the long and short rebinned images should contain definitions identified by `s1reb' and `s2reb' whereas `reb' would be relevant if only 1 sub-instrument is being processed.
