The LS DR11 tractor catalog 'type' column contains catalog identifiers (ie. 'G3'), while 'ref_cat' contains the morphological information (ie. 'PSF', 'DUP', etc.). This disagrees with the format used in the other tractor catalogs and the catalog column name description (they should be swapped I believe). I have not checked if any other column names are misaligned.
This can problem can be seen with a simple query like:
SELECT t.ref_cat, t.type
FROM ls_dr11.tractor AS t
WHERE t.brick_primary = 1 AND q3c_radial_query(t.ra, t.dec, 300,1,0.03)
