sSFR functions per redshift bin from 0.2 <z< 0.4 to 1.2 <z< 1.4 (from the top to the bottom rows) and per stellar mass bin from 9.5 < log (M⋆) < 10 to 11 < log (M⋆) < 11.5 (from the left to the right columns). The black solid lines and green dashed lines correspond to the best-fit sSFR_UV+IR functions assuming a double-exponential and a log-normal profile, respectively (as shown in Fig. 4). The dotted lines correspond to the same function convolved with a Gaussian having σ = 0.3 dex to mimic the expected uncertainties on SFR_SED. The sSFR_NRK functions are shown with blue error bars and dashed lines. They are derived using an optical tracer of the SFR developed by Arnouts et al. (2013). The red and orange lines are obtained using SFR_SED with and without a correction for possible biases in SFR_SED.
