Comparison of sSFR and UVJ classification for the 3 < z < 4 galaxies with M_* > 3  ×  10¹⁰ M_⊙ in ZFOURGE (COSMOS and UDS). The sSFR are displayed on the left (best fits on the left, and upper limits on the right), while UVJ colors are shown on the right. UVJ-quiescent galaxies are highlighted in red. Galaxies outside of the quiescent region but with sSFR < sSFR_Q = 0.15 Gyr⁻¹ are labeled with green and blue open symbols, depending on whether they are in the “dusty” or “non-dusty” part of the UVJ diagram (respectively), as delimited with the diagonal dotted line (U − J  =  2.6).
