SED-derived star formation rate as a function of stellar mass. The MASSIV sample (black filled squares) is compared with other major IFU surveys of distant galaxies: IMAGES (z ~ 0.4−0.75, blue circles), SINS (z ~ 1.4−2.6, magenta triangles), OSIRIS (z ~ 1.5−3.3, green crosses), and LSD/AMAZE (z ~ 2.6−3.8, red asterisks). The lines represent the empirical relations between SFR and stellar mass for different redshifts between z = 0 and z = 3 following the analytical expression given in Bouché et al. (2010). For comparison between the different samples, a scaling factor of +0.25 dex (SINS, OSIRIS, and LSD/AMAZE samples) or +0.15 dex (IMAGES sample) has been applied to the published stellar masses and star formation rates.
