Differential SMFs in the redshift range 2.0 <  z <  2.5 using our reference model without relative scatter. Black dotted, black dashed, and blue dashed lines represent the SMF of the ΛCDM DUSTGRAIN-pathfinder simulation (calculated using the reference model on the comoving boxes), without observational scatter, a fixed scatter (with σ_obs = 0.25 dex), and a scatter that varies with redshift (with σ_obs = 0.04(1 + z) dex), respectively. With open red circles we show the 1/V_max points by Ilbert et al. (2013) and with a dotted red line (and corresponding shaded area) their intrinsic best-fit Schechter function. With green, cyan, and magenta open points we show results from Tomczak et al. (2014), Santini et al. (2012), and Mortlock et al. (2011), respectively.
