Separation criteria from Messias et al. (2012) using the Spitzer/IRAC 4.5 and 8.0 μm bands, the Spitzer/MIPS 24 μm band, and the K_s band. The dashed line outlines the area where AGNs could be found based on the IM criteria. The red empty circles indicate the objects that also met the KIM criteria. The colour-coding represents the spectroscopic redshift of the objects. The average 1σ size is shown in red at the bottom left.
