is a powerful image display and analysis tool. It provides the usual facilities of
image display tools, plus more astronomically useful ones such as aperture
& optimal photometry, contouring, source detection, surface photometry,
arbitrary region analysis, celestial coordinate readout, calibration and
modification, grid overlays, blink comparison, defect patching and the
ability to query on-line (WWW) catalogues.
KAPPA comprises about 180 general-purpose
commands for image processing, data visualisation, and manipulation of the standard
Starlink data format -- the NDF.
