This script converts a FITS file of your choice to a ".z" (ascii)
file as used by GLE when creating image "colormaps". This can then be used
to create awesome figures such as the Volcano example used on the
GLE examples page here.
This script creates an image (a colourmap) of any FITS file,
giving the figure appropriate WCS axis labels according to the FITS
header information. This is a useful way of creating a GLE
template, which can be edited and tweaked as required.
