Illustration of how measurement uncertainties taken from posterior distributions for local SFR and local stellar mass are used to construct the posterior distribution for LsSFR. Top left: the local log(SFR); lower left: the local log(M_*/M_⊙) (see also Fig. 2); right: the resulting local log(sSFR). The vertical grey solid lines indicate the median of each distribution, and the two dashed lines delimit the 16th to 84th percentile range. On the LsSFR plot, the thick vertical black line shows log(LsSFR_cut) = − 10.8. This figure again exemplifies a moderate signal to noise ratio case using the host galaxy for SNF20060912-004.
