radial_profiles.einasto_mass_profile# radial_profiles.einasto_mass_profile(M, r_s, n)[source]# A mass profile where the logarithmic slope is a power-law [Eina65]. The form here is that given in Section 2 of [RvGB12]. Parameters: M (float) – The total mass of the profile in M. r_s (float) – The scale radius in kpc. n (float) – The inverse power-law index. Returns: The corresponding radial profile object. Return type: RadialProfile
