Correlation between rest-frame U− V color and sSFR for massive galaxies in the three redshift bins. The red symbols represent galaxies in the "passive" UVJ color–color box (see Figure 5); the black symbols represent star-forming galaxies. Our selection criterion for early-type galaxies is based on an sSFR cut (sSFR < 1/3 t _H( z)), here illustrated by the horizontal, dotted lines which correspond to the sSFR cuts in the center of the redshift bins. For all redshift bins, the two types of galaxies are neatly separated; moving the sSFR cut by a modest amount does not strongly affect our selection of early-type galaxies. Note that aliasing occurs for low-sSFR objects as a result of template choices in the SED fitting.
