sSFR functions combined at z = 0 correcting the 1/V_max data from the redshift evolution derived in Sect. 4.3. Each panel corresponds to a stellar mass bin. The black triangles are obtained with the 1/V_max estimator over the COSMOS and the GOODS fields (mixed together in this figure). The green arrows are lower limits in the 1/V_max estimate. The red solid lines and blue dashed lines correspond to the best-fit of a double-exponential and a log-normal function over the 1/V_max data. The blue dotted line corresponds to the fit of a Gaussian function without including a starburst component. The inset in each panel shows the distribution of the differences between the best-fit function and the data, with a density dispersion of 0.19 dex at log (M⋆) = 9.5−10, 0.11 dex at log (M⋆) = 10−10.5, 0.09 dex at log (M⋆) = 10.5−11, and 0.07 dex at log (M⋆) = 11−11.5, as shown by the vertical dashed lines.
