Upper panel: the total BOSS stellar mass function at ﹩z=[0.45,0.60]﹩, down to our completeness limit of ﹩\mathrm{log}{M}_{* }=11.4﹩. The best-fit parameters of equation (x) are shown with the solid curve. Lower panel: residuals of the fit. The y-axis is ﹩({{\rm{\Phi }}}_{\mathrm{BOSS}}-{{\rm{\Phi }}}_{\mathrm{fit}})/{{\rm{\Phi }}}_{\mathrm{fit}}﹩. The ﹩{\chi }^{2}﹩ for this fit is 7.0 for (10–5) degrees of freedom.
