Abstract:
We present a catalog of 13444 SDSS-DR5 spectroscopic quasars which
have an 2MASS near-IR counterpart within 5" of their position.
Description:
We cross-correlate the SDSS Data Release 5 (DR5) spectroscopic quasars
with Two Micron All Sky Survey (2MASS) point sources (Cutri et al.
2003, Cat. II/246). Specifically we look for a 2MASS point source
within 5" from each quasar position and extract its IR magnitudes and
radio flux in the FIRST catalogue (Becker et al., 1995, See Cat.
VIII/71).
