VizieR Online Data Catalog: Ultraviolet Extinction in the GALEX Bands. UVEXT (Sun+, 2018)

The Ultraviolet Extinction in the GALEX Bands (UVEXT) catalog is obtained by using the GALEX, APASS, LAMOST surveys. The cross-match is carried out with a radius of 3". The GALEX DR6/7 and APASS DR9 catalogs are cross-matched first. This GALEX-APASS catalog is further cross-identified with the LAMOST spectroscopic survey. This catalog includes 25496 stars in the northern sky. The limiting magnitude are B,V<17, NUV<21mag and FUV<20mag, and the photometry accuracy is better than 0.05 in the V,B band, 0.20mag in the NUV band and 0.30mag in the FUV band. The color excesses in the GALEX bands, E(NUV-B) and E(FUV-B), are listed.
