into regions heavily contaminated by YSOs and one that should principally contain quasars, based on mid-IR properties of YSOs from [@2008AJ....136...18W] and the mid-IR data from the 9 deg$^2$ of the Spitzer Deep Wide-Field Survey (SDWFS; @2009ApJ...701..428A) of spectroscopically confirmed quasars from the AGN and Galaxy Evolution Survey (AGES; @2011arXiv1110.4371K). Finally, the candidates were classed as “a” if they had the optical-to-mid-IR colors of quasars in AGES and “b” if they did not.

The most interesting candidates are classed as QSO-Aa (quasar region, away from blackbody locus with QSO optical-to-mid-IR colors), but given the large number of AAOmega fibers, we targeted all classes of objects, excluding only those marked as “outside” (of the OGLE-III fields) or “faint” (not detected on the OGLE-III template images).

X-Ray-selected AGN Candidates
-----------------------------

We searched for the OGLE-III counterparts to the 758 X-ray sources distributed over $10\times10$ deg$^2$ of the LMC from . The typical positional uncertainly for these X-ray sources is several arcseconds, so we cannot effectively target them without some additional selection criterion given the stellar densities. As a second criterion we chose the most optically variable source within $3\sigma$ of the X-ray position. In this case, variability simply means that the light
