– 28 – Fig. 7.— Left panel: mid-IR color-color distribution of the Photometry Group 3, Vari- ability Level 2 sources with spectroscopic redshifts from AGES. Stars, circles, and squares correspond to objects with stellar, galaxy, or AGN spectroscopic template matches. The contours show the distribution of galaxies (gray), stars, and AGNs with AGES redshifts. Right panel: fraction of objects with stellar, galaxy, or AGN template matches (dotted, dashed, and solid line, respectively) that are the Photometry Group 2, Variability Level 2 variables as a function of [3 . 6] − [4 . 5] color.
