Galaxy stellar mass functions of the blue and red populations in VIPERS, derived using the 1/V_max. Symbols (circles and diamonds, respectively) are filled for data above the corresponding completeness limit ℳ_lim (vertical lines) and empty below. Error bars account for Poisson noise alone. The Schechter fit of the two populations in the bin 0.5 < z < 0.6 (solid blue and red lines) is reported for reference as a dashed line in the other panels. The solid black line in each panel gives the Schechter best fit to the whole VIPERS sample in that redshift bin.
