The Einasto profile possesses a power law logarithmic slope of the form: γ γ ( r ) ≡ ≡ − − d ⁡ ⁡ ln ⁡ ⁡ ρ ρ ( r ) d ⁡ ⁡ ln ⁡ ⁡ r ∝ ∝ r α α which can be rearranged to give ρ ρ ( r ) ∝ ∝ exp ⁡ ⁡ ( − − A r α α ) . The parameter α α controls the degree of curvature of the profile. This can be seen by computing the slope on a log-log plot: d ln ⁡ ⁡ ρ ρ d ln ⁡ ⁡ r ∝ ∝ − − r α α .
