Results of KS test between VIPERS and SDSS samples in order to check evolution of MZR and metallicity-SFR relation. The top panel shows the p value of the KS test performed in M_⋆ bins for the MZR (dots) and SFR bins for the metallicity-SFR relation (diamonds). The bottom panel is the same as the top panel, but we report the product of the sequence for X > x where X is the M_⋆ or the SFR and x is the value on the x-axis. The dashed horizontal line (y = 0.05) shows the threshold for the 95% confidence level of the KS test.
