Dependence of the mass function on the details of the stellar mass estimates, considering five different cases. Specifically, the points correspond to different choices of the stellar population synthesis code, metallicity (Z), extinction law (SB+SMC or SB alone), or the addition of secondary bursts to the smooth star-formation histories. Four cases correspond to SED fitting using Hyperzmass, for which the values of the adopted parameters are given in the bottom-left of the first panel. For details about the parameters adopted for MAGPHYS (downward triangle), we refer to Sect. 2.3.
