Sorry I didn't get to it sooner; I just discarded it since you reposted.

Yes, that's the right format.

Ok, I'll see what I can do...

We'll have to do some investigation to make sure that the wikipedia
mags are more accurate than the kstars mags when they disagree.  We
don't need to do this for all objects, just pick a handful from the
top and bottom of the list (with the biggest delta-mag values) and
look them up with SIMBAD.

Does wikipedia have the IC catalog as well?
