| Abstract: |
We positionally match sources observed by the Sloan Digital Sky Survey (SDSS) to sources observed by the Two Micron All Sky Survey (2MASS) and the FIRST radio survey in ~200 deg2 of high-latitude sky along the Celestial Equator. There are ~3x106 SDSS sources, ~2x105 2MASS sources, and ~2x104 FIRST sources in this region. Practically all (~98%) 2MASS sources are matched to an SDSS source within 2 arcsec; ~14% of them are optically resolved galaxies and the rest are dominated by stars. About 33% of FIRST sources are matched to an SDSS source within 2 arcsec; about 78% of these are galaxies and the rest are dominated by quasars. We will present detailed statistics of the optical, infrared and radio properties for the extragalactic sources from the matched sample. |
