survey of galaxies to $i\sim23$ [@Coil11; @Cool13]. From the parent sample of $\sim120,000$ robust redshifts, @Moustakas13 constructed a flux-limited sample of $\sim40,000$ galaxies at $0.2<z<1.0$ over an area coverage of $5.5$ deg$^2$. Stellar masses were determined using fits to the observed spectral energy distributions (SEDs) based on ultra-violet, optical, near-infrared and mid-infrared photometry from *GALEX*, *Spitzer*/IRAC and a range of ground-based imaging campaigns [see @Moustakas13 for full details]. The SMF was constructed using the $V_\mathrm{max}$ method, carefully accounting for the PRIMUS targeting weights and redshift success rates, in six redshift bins between $z=0.2$ and $z=1.0$ (corresponding to roughly equal intervals of cosmic time). For this study we adopt Schechter fits to the total SMF in each individual redshift bin, fully propagating the covariant uncertainties in the model fit parameters. A single Schechter form may not provide a full description of the shape of the SMF, but it does provide a good fit for the range of redshifts and stellar masses considered here. The Schechter fits allow us to smooth between the $V_\mathrm{max}$ measurements in different stellar mass bins and perform moderate extrapolation to lower and higher stellar masses.

The @Moustakas13 results indicate remarkably little evolution in the global SMF of
