Notes.

^(a)

Right ascension expressed in decimal hours (J2000).

^(b)

Declination expressed in decimal degrees (J2000).

^(c)

AB magnitudes from GALEX.

^(d)

AB magnitudes from RCS-2.

^(e)

Photometric error in the magnitudes from GALEX.

^(f)

Photometric error in the magnitudes from RCS-2.

^(g)

Whether the object is classified as a quasar from the corresponding data set. If true, it is 1. If not, it is 0.
