Description

This object implements the NcHaloDensityProfile class for a Diemer \& Kravtsov (DK14) density profile.

The DK14 profile is defined as ... Implementation incomplete! FIXME

Functions

nc_halo_density_profile_dk14_new ()

NcHaloDensityProfile *
nc_halo_density_profile_dk14_new (void);

This function returns a NcHaloDensityProfile with a NcHaloDensityProfileDK14 implementation.

Returns

A new NcHaloDensityProfile.

Types and Values

enum NcHaloDensityProfileDK14Params

The first three parameters, $\rho_s$, $r_s$ and $\alpha$, are the Einasto profile's parameters. The transition term $f_{trans}$ is a function parametrized by $r_t$, $beta$ and $\gamma$. These two functions determine the inner profile, whereas the outer profile is parametrized br $b_e$ and $s_e$.

Members

NC_HALO_DENSITY_PROFILE_DK14_RT	the truncation radius, the radius where the profile steepens beyond the Einasto profile, in $kpc/h$
NC_HALO_DENSITY_PROFILE_DK14_BETA	sharpness of the steepening
NC_HALO_DENSITY_PROFILE_DK14_GAMMA	asymptotic negative slope of the steepening term
NC_HALO_DENSITY_PROFILE_DK14_BE	amplitude of one factor of the outer profile.
NC_HALO_DENSITY_PROFILE_DK14_SE	slope of the outer profile.
