Perhaps you could give some examples of where the conversion programs is not
working for numpy.

So, before pursuing in this direction, I'd like to know if this exercice has

Have you contacted the author of the package? The website states that the
package has been tested on the IDL astronomy library, so he should be able
to give you idea of how successful it was. If you do hear back from him I'd
be interested to know how successful this project is, as I'm always looking
for reasons to convert users in my astronomy department from things like IDL
on to python :-)
