Caption: Figure 3.

Top left: a two-dimensional histogram of ﹩\mathrm{log}({M}_{* }/{M}_{\odot })﹩ and ﹩\mathrm{log}({\rm{sSFR}}/{{\rm{yr}}}^{-1})﹩ from the posterior draws of all mF444W < 24 spectroscopically confirmed galaxies modeled with Prospector. The individual galaxies and their uncertainties are indicated by black/blue/red/pink for galaxies classified as ﹩\mathrm{log}({M}_{* }/{M}_{\odot })\lt 10.5﹩/﹩\mathrm{log}({M}_{* }/{M}_{\odot })\,\geqslant \,10.5﹩ star-forming/﹩\mathrm{log}({M}_{* }/{M}_{\odot })\,\geqslant \,10.5﹩ quiescent/﹩\mathrm{log}({M}_{* }/{M}_{\odot })\,\geqslant \,10.5﹩ marginally quiescent based on their inferred posterior medians. The red box denotes the region we use to define MQGs. Top middle: same as the left, but for ﹩\mathrm{log}({\rm{sSFR}}/{{\rm{yr}}}^{-1})﹩ and optical depth τdust. Galaxies with high τdust and low sSFR appear to be dusty star-forming galaxies based on visual inspection of their spectra and SEDs. Top right: same as the left, but for ﹩\mathrm{log}({M}_{* }/{M}_{\odot })﹩ and dust optical depth τdust. Bottom row: the same layout as the top row, except showing the inferred properties from galaxies with only fits to photometry at zspec in Section 3.3.
