astrometry_net_data catalogs at NCSA

I’ve just declared a 2mass.20130404 version of astrometry_net_data in the stacks at NCSA, having found the files already present in /lsst7/astrometry_net_data. These seem to match a catalog we have on our HSC processing machines in Princeton and Japan, so I assume it’s in reasonably good shape (though we mostly process HSC data using a PanSTARRS catalog that we can’t distribute). @price may know more.

There’s also an sdss-dr9-fink-v5b, also transferred from HSC, and I think it represents the safest bet for any verification data processing (assuming the data is within the SDSS footprint).

I added usnob a week or so ago, but I think @nidever found it didn’t work (it lacks the photometric information). It should be usable again when we split the astrometric and photometric standards (and if we accept the astrometry.net standard as a possible backend)
