SN rates in SNuM vs. sSFR for Type Ia (left panel) and CC SNe (right panel) in three different groups of galaxies based on their sSFR: the first group of passive galaxies with a zero mean SFR; the second group of galaxies with −12.0 < log (sSFR) < −9.5; third group of galaxies with log (sSFR) > −9.5. In both panels the circles are from SUDARE, the triangles from Mannucci et al. (2005), the squares from Sullivan et al. (2006), the pentagons are from Smith et al. (2012) and the diamonds from Graur et al. (2015). The literature values have been corrected to a Salpeter IMF.
