URAT1 is an observational catalog at a mean epoch between 2012.3 and 2014.6; ot covers the magnitude range 3 to 18.5 in R-band, with a positional precision of 5 to 40 mas. It covers most of the northern hemisphere and some areas down to -24.8° in declination.

In the GAVO data center, we left out all columns originating from cross matches with other catalogs; on-the fly crossmatches can be done in our TAP service.
