XMatch.query missing cat1 when usign two previously uploaded tables

[masgura]

Hi, I'm trying to match two previously uploaded catalogue this way:

radec_mid = SkyCoord(a_mid, d_mid, unit=(u.deg, u.deg))
columns = ['Gmag', 'BP-RP', 'RAJ2000', 'DEJ2000', 'ra', 'dec', 'pmra', 'mpdec', 'source_id']
custom_visizer = Vizier(columns=columns)
custom_visizer.ROW_LIMIT = -1

astropy.utils.data.clear_download_cache(hashorurl=None, pkgname='astropy')

stars_1 = custom_visizer.query_region(radec_mid, radius=self.telescope.fov, catalog='I/355/gaiadr3',
                                    **kwargs)
stars_2 = custom_visizer.query_region(radec_mid, radius=self.telescope.fov, catalog='I/350/gaiaedr3',
                                      **kwargs)

stars = XMatch.query(cat1=stars_1[0], cat2=stars_2[0], max_distance=1 * u.arcsec, colRA1='RAJ2000',
                     colDec1='DEJ2000', colRA2='RAJ2000', colDec2='RAJ2000')

I checked that the two tables are correctly uploaded, but the XMatch.query function gives me this error:

Message: Missing parameter "cat1".
                 Trace:

But, then I do it this way:

stars = XMatch.query(cat1=stars_1[0], cat2='vizier:I/350/gaiaedr3, max_distance=1 * u.arcsec, 
                    colRA1='RAJ2000', colDec1='DEJ2000' )

Everything works fine

I can reproduce. But why don't you directly crossmatch the online versions of the catalogs? Is there something that does not allow you to use the second version?

Since I need only some columns, I noted that uploading the catalogue by column names is way faster than using the whole catalogue (7 seconds compared to 1/2 minutes), so I was trying to check if uploading both + matching them is faster than uploading the first and matching it with the online one (which takes about 25-30 seconds). Matching the two online versions is waay slower

Were you able to try again? It should be fixed in the development version, see here to see how to install it: Building from source

Sorry for the late replay, everything works fine now, thanks!
