$z\!\sim$2.

This selection method is enabled by the increased resolution provided by the near-IR medium-bandwidth filters. The improved sampling of the SEDs enable robust constraints on both the photometric redshifts ($\sim$2% accuracies compared to the $\sim$6-7% accuracies of broad-band $z_{\mathrm{phot}}$ when using all available spectroscopic redshifts) as well as the dust content of the stellar populations [see @Brammer09]. The typical upper and lower 68% confidence intervals on the dust extinction (for both quiescent and star forming galaxies) range from $^{+0.3}_{-0.3}$ at $z\!\sim0.5$ to $^{+0.2}_{-0.1}$ at $z\!\sim2$. Furthermore, the inclusion of IRAC data helps constrain the overall shape of the SED and significantly improves the confidence intervals of the dust extinction for the individual galaxies [e.g. @Labbe05; @Wuyts07; @Muzzin09]. About 20% of the quiescent galaxies have no IRAC coverage as we did not make any restrictions in our selection method, which may imply that their classification as quiescent is less robust [see, e.g., @Labbe05]. We verified that these 20% of objects do not deviate systematically from the trends we see for the sample of objects with IRAC coverage. We note that this selection method is consistent with the $UVJ$-selection, which does not depend on models (see Appendix A.).
