double GModelSpatialRadialProfileDMEinasto::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:

\[ f(\theta, l) = E^{ -\frac{2}{\alpha} \left( g^{\alpha} - 1 \right) } \]

where

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