Comparison of sSFR estimates from several sources: SED modeling with FAST++ (black), Hβ luminosity (blue), [O II] luminosity (green), and, when available, L_IR from ALMA (orange). The error bars for all quantities indicate the 90% confidence interval. The line luminosities were corrected for dust attenuation using the A_V from the SED modeling. Each galaxy with a spectroscopic redshift at z > 3 is shown in a different column. For visualization purposes we limit the minimum sSFR to 10^-3 Gyr^-1, which is indicated with the dotted line; galaxies on this line are actually at lower sSFR. The blue horizontal line gives the average sSFR of main-sequence galaxies (see Sect. 4.4).
