Specific star formation rate as a function of stellar mass for the VGS and CCS with all the galaxies (left), and only star-forming galaxies (right). The mean sSFR per M_⋆ bin is shown with a red symbol (connected by a solid red line to guide the eye) for the VGS, and with a blue symbol (and dashed blue line) for the CCS. The error bar in M_⋆ represents the width of the stellar mass bin. The GASS sSFR main sequence is represented as solid black line. This is a fit to the main-sequence galaxies carried out by Saintonge et al. (2017). The dashed black line is the limit chosen by us to select star-forming galaxies (see Sect. 3).
