Method

NumCosmoWLSurfaceMassDensitysigma_excess

Declaration [src]

gdouble
nc_wl_surface_mass_density_sigma_excess (
  NcWLSurfaceMassDensity* smd,
  NcHaloDensityProfile* dp,
  NcHICosmo* cosmo,
  const gdouble R,
  const gdouble zc
)

Description [src]

Computes difference between the mean surface mass density inside the circle with radius R (Eq. $\eqref{eq:sigma_mean}$) and the surface mass density at R (Eq. $\eqref{eq:sigma}$).

Parameters

dp

Type: NcHaloDensityProfile

A NcHaloDensityProfile.

The data is owned by the caller of the method.

cosmo

Type: NcHICosmo

A NcHICosmo.

The data is owned by the caller of the method.

R

Type: const gdouble

Projected radius with respect to the center of the lens / halo.

zc

Type: const gdouble

Cluster redshift $z_\mathrm{cluster}$.

Return value

Type: gdouble

$\overline{\Sigma} (<R) - \Sigma (R)$.
