Dear group,

maybe this is interesting for some of you. I ported some of the
functionality of the IDL astrolib library to Mathematica to enable the
overlay of an celestial coordinate grid on top of an astronomical FITS
image. I also used the new Documentation building capabilities of
Workbench 2.0 to build some help pages and bundled everything
together.

The result is something I called WCSTools and can be downloaded from
my website:

The package is still very much in beta status but usable
nevertheless.

Cheers,

Markus Roellig
