QSOs in the Combined SDSS/GALEX Database

We discuss selection of QSO candidates from the combined SDSS and GALEX catalogs. We discuss properties of QSOs within the combined sample and note uncertainties in number counts and completeness, compared with other SDSS-based samples. We discuss color and other properties with redshift within the sample and the spectral energy distributions for subsets. We estimate the numbers of faint QSOs that are classified as extended objects in the SDSS imaging and consequent uncertainties that follow.
