While the astrometric matches are sometimes imperfect, we are dealing with objects with such low surface densities that a mismatch is extraordinarily unlikely. Essentially, this search recapitulates aspects of the Kozowski et al. (2010) search for quasars behind the Magellanic clouds as red mid-IR sources following the extragalactic mid-IR search criteria of Stern et al. (2005). The red mid-IR colors created by the power-law SEDs of quasars mimic aspects of the red SEDs of dusty stars.
