VizieR Online Data Catalog: SDSS-Spitzer type I QSOs IR photometry (Richards+, 2006)

We investigate the mid-IR and optical properties of type 1 quasars that are detected in both the SDSS and in all four bands of the Spitzer Infrared Array Camera (IRAC). The Spitzer data are taken from the XFLS and SWIRE ELAIS-N1, ELAIS-N2, and Lockman Hole areas, which have (RA, DE) centers of (259.5{deg}, 59.5{deg}), (242.75{deg}, 55.0{deg}), (249.2{deg}, 41.029{deg}), and (161.25{deg}, 58.0{deg}), respectively.
