  const gdouble lnr
)

Description [src]

Evaluates the first derivative of the logarithm of the filtered variance with respect to $\ln r$ at lnr and z.

Parameters

z

Type: const gdouble

Redshift $z$.

lnr

Type: const gdouble

Logarithm base e of $r$.

Return value

Type: gdouble

$\frac{\mathrm{d} \left[ \ln \sigma^2(\ln r, z) \right] }{\mathrm{d} \ln r }$.
