Function

NumCosmoXcorLensingEfficiencyEvalSource

Declaration

gdouble
(* NcXcorLensingEfficiencyEvalSource) (
  NcXcorLensingEfficiency* lens_eff,
  gdouble z
)

Description [src]

Evaluates the source weight function $W_{\mathrm{src}}(z)$ for the lensing efficiency computation. This is used in the integral: \begin{equation} g(z) = \int_z^{z_{\max}} dz’ \left(1 - \frac{\chi(z)}{\chi(z’)}\right) W_{\mathrm{src}}(z’) \end{equation}.

Parameters

lens_eff

Type: NcXcorLensingEfficiency

A NcXcorLensingEfficiency.

The data is owned by the caller of the function.

z

Type: gdouble

Redshift.

Return value

Type: gdouble

$W_{\mathrm{src}}(z)$.
