Issue with UKIDSS catalog query about astroquery

[keflavich]

Thanks. I suspect this has to do with the catalog specification; I've seen
something like it before

@keflavich https://github.com/keflavich - feel free to look into it if

The problem is that I changed the default programmID to be 'all', which makes sense for images, but is not allowed for catalogs. I've now added a verify_programme_id function, so instead of returning nothing, the above query will raise a sensible error. The solution, though, is to change the programmeID:

Q.programmeID = 102

or

Q.programmeID = 'GPS'
