pywcs 1.10-4.7

Python wrappers to WCSLIB

Introduction

pywcs is a set of routines for handling the FITS World Coordinate System (WCS) standard. It is a thin wrapper around the high- and mid-level interfaces of Dr. Mark Calabretta’s WCSLIB available here:

In addition, there are extensions (written in C) to support Spitzer Simple Imaging Polynomial (SIP) convention keywords and Paper IV table lookup distortion.

Build instructions

pywcs includes its own copy of WCSLIB.

pywcs requires:

• Numpy 1.3 or later

• pyfits 1.4 or later

pywcs uses the standard Python distutils system to build and install itself. From the command line run:

python setup.py install

to install pywcs.

Building documentation

Optionally, the documentation can be built using Sphinx (http://sphinx.pocoo.org).

After installing pywcs, ‘cd’ into the ‘doc’ directory and:

make html

The documentation is also available online at:
