inline

double GModelSpatialRadialProfileDMBurkert::halo_kernel_los::eval ( const double & los )

virtual

Kernel for halo density profile squared.

Parameters

[in] los Distance from observer to point in space (meters).

Computes the value of an einasto halo density profile squared, at distance l from observer, at angle

\[\theta\]

from the halo center:

\[ f(\theta, l) = \frac{r_{scale}^3}{ \left( r + r_{scale} \right) \left( r^2 + r_{scale}^2 \right)} \]

where

\[ r = \sqrt{l^2+d^2-2ldCos(\theta)} \]
