Methods of diskdf instances (shudf or dehnendf), illustrated using a Dehnen DF with a flat rotation curve (β = 0 in v_c(R) = v_c(R₀) (R/R₀)^β) with Σ(R)∝exp [ − R/(R₀/3)] and σ_R(R) = 0.2 exp [ − (R − R₀)/R₀]. The df object does not apply corrections to these profiles, while the dfc object does, with 20 iterations of the correction procedure (see text). The results on the moments of the uncorrected DF can be directly compared to Figure 4 of Dehnen (1999).
