Fig. 7

As for the upper left panel of Fig. 5, but for the local specific star formation rate, sSFR(R) = ΣSFR(R) /μ⋆(R). The error bar shows the 1σ dispersion in log sSFR for Sb galaxies. The gray dashed line at sSFR = 0.1 Gyr-1 indicates the value adopted by Peng et al. (2010) as a threshold for separating star-forming galaxies from quiescent systems.
