Distribution of ﹩\mathrm{log}\ \mathrm{sSFR}/\left\langle \mathrm{sSFR}\right\rangle ﹩ in bins of stellar mass: the entire M_* range and ﹩\mathrm{log}{M}_{* }/{M}_{\odot }=\left[{\rm{9.4:9.9}}\right]﹩, ﹩\left[{\rm{9.9:10.4}}\right]﹩, ﹩\left[{\rm{10.4:10.7}}\right]﹩, and ﹩\left[{\rm{10.7:11.5}}\right]﹩ (left to right). The average ﹩\left\langle \mathrm{sSFR}\right\rangle ﹩ is taken from the best fit with the asymptotic function (Equation (13)) at each M_*. Blue solid lines indicate the best-fit functions assuming a lognormal profile with mean values indicated by vertical dotted lines. Blue dashed lines indicate lognormal functions with the estimated intrinsic scatter (σ_int). The median error of SFR﹩{}_{{\rm{H}}\alpha }﹩ in each bin is indicated by a horizontal error bar in each panel.
