KAPPA — Kernel Application Package
Kappa is an applications package comprising about 180 general-purpose commands for image processing, data visualisation, and manipulation of the standard Starlink data format—the NDF. It is intended to work in conjunction with starlink’s various specialised packages.
In addition to the NDF, Kappa can also process data in other formats by using the ‘on-the-fly’ conversion scheme. Many commands can process data arrays of arbitrary dimension, and others work on both spectra and images. Kappa operates from both the UNIX C-shell and the ICL command language.
This document describes how to use Kappa and its features. There is some description of techniques too, including a section on writing scripts. This document includes several tutorials and is illustrated with numerous examples. The bulk of this document comprises detailed descriptions of each command as well as classified and alphabetical summaries.
