OSQSONVSS - Optically-Selected QSOS NVSS-Detected Source Catalog
The SDSS DR7 QSO catalog (Schneider et al. 2010, AJ, 139, 2360) is complete to i = 19.1 mag over a solid angle of 2.66 sr around the North Galactic Pole. It contains the small sample of 179 color-selected QSOs defined by Mi < -23 in the narrow redshift range 0.2 < z < 0.3 studied by Kimball et al. (2011, ApJ, 739, L29) and the larger sample of 1,313 QSOs in the wider redshift range 0.2 < z < 0.45 discussed here. Note that these magnitudes were calculated for an H0= 71 km/s/Mpc and OmegaM = 0.27 modern flat LambdaCDM cosmology. The entire SDSS DR7 area is covered by the NVSS, whose source catalog is complete for statistical purposes above a peak flux density Sp ~ 2.4 mJy/beam at 1.4 GHz. In the redshift range 0.2 < z < 0.45 the 45" FWHM (full width between half-maximum points) beam of the NVSS spans 150 - 250 kpc. There are 163 (12%) NVSS detections of the 1,313 QSOs in the redshift range 0.2 < z < 0.45 which are listed in Table 1 of the reference paper.
The authors also chose a magnitude-limited sample of all 2,471 color-selected DR7 QSOs brighter than mr = 18.5 in the redshift range 1.8 < z < 2.5. The NVSS detected radio emission stronger than S = 2.4 mJy from only 191 (8%) of them: these are listed in Table 3 of the reference paper.
This HEASARC table contains the contents of both samples described above. It thus has 163 + 191 = 354 entries, the sum of Tables 1 and 3 from the reference paper. To select only the entries from Table 1, the user should select entries with redshifts from 0.2 to 0.45. To select only the entries from Table 3, the user should select entries with redshifts > 1.8.

The SDSS source designation of the QSO in the standard form. This was not given explicitly in the original tables but was constructed by the HEASARC from the listed J2000.0 equatorial positions.
The Right Ascension of the QSO in the selected equinox. This was given in J2000.0 equatorial coordinate to a precision of 0.01 seconds of time in the original table.
The Declination of the QSO in the selected equinox. This was given in J2000.0 equatorial coordinate to a precision of 0.1 arcseconds in the original table.
The Galactic Longitude of the QSO.
The Galactic Latitude of the QSO.
The SDSS-DR7 redshift of the QSO.
The absolute i-band magnitude of the QSO. See the Overview above for the details of the adopted cosmological model.
