NumCosmoXcorKernelRadialKDep

Description [src]

abstract class NumCosmo.XcorKernelRadialKDep : GObject.Object
{
  /* No available fields */
}

Closed-form scale dependence that a NcXcorKernelRadial can carry.

Attached to a kernel, it multiplies the radial integrand, \begin{equation} K(\chi,k) = W(\chi)\,g(\chi,k)\,\sqrt{P(k, z=0)} , \end{equation}

which is what makes the integrand genuinely a function of both variables. A kernel without one has $g \equiv 1$, and its radial integral is the same shape at every $k$ up to an overall factor.

That separability is not a detail: a method that reduces the radial integral to a single transform of $W$ can only produce a $k$-independent shape, so it cannot represent this at all. Any shape can carry any scale dependence, so the two vary independently in a benchmark rather than being baked into separate kernel classes.

Note that a code compared against this must be able to evaluate a $k$-dependent kernel at all; several cannot, and that is the claim the construction exists to exercise rather than a limitation of it.
