We are pleased to announce the release of version 2.0.2 of the Kapteyn Package.
The Kapteyn Package is a collection of Python modules developed by the
computer group of the Kapteyn Astronomical Institute, University of
Groningen, The Netherlands.
Some of the package's features:
- The handling of spatial and spectral coordinates, WCS projections and
transformations between different sky systems. Spectral translations
(e.g. between frequencies and velocities) are supported as well as
mixed coordinates. For WCS, Dr. Mark Calabretta's WCSLIB is used.
- Versatile tools for writing small and dedicated applications for the
inspection of FITS headers, the extraction, display and interactive
inspection of (FITS) data and for the creation of plots with world
coordinate information, including all-sky plots.
A unique feature is the possibility to make plots with mixed
coordinates, e.g. where one axis is spatial and the other one is
spectral. Matplotlib and PyFITS are used.
- Tools for parsing and interpreting coordinate information entered by
- Utilities for use with Matplotlib such as obtaining coordinate
information from plots, interactively modifiable colormaps and timer
events (to facilitate movie loops).
- A class for the efficient reading, writing and manipulating of simple
table-like structures in text files.
Currently supported architectures are Linux, Apple Mac OS X and
Extensive documentation, including tutorial and background information,
as well as download and installation instructions can be found at
We look forward to your feedback.
