The Subaru/XMM-Newton Deep Survey (SXDS)

B=28.4, V=27.8, Rc=27.7, i’=27.7 and z’=26.6, 1.22 deg^2

Measuring the Fraction of Obscured Quasars by the Infrared Luminosity of Unobscured Quasars
http://arxiv.org/abs/0801.3849
collected archival 24 micron MIPS photometry from objects with z~1 in SDSS, GOODS, and COSMOS.
Although we find approximate agreement, our method indicates somewhat higher values of f_obsc, particularly in the middle range of luminosities, suggesting that there may be a significant number of heavily obscured AGN missed by X-ray surveys.
