class SourceDirectedEmission : public SourceFeature 

Directed emission from a source from the von-Mises-Fisher distribution.

The emission from the source is generated following the von-Mises-Fisher distribution with mean direction mu and concentration parameter kappa. The sampling from the vMF distribution follows this document by Julian Straub: http://people.csail.mit.edu/jstraub/download/straub2017vonMisesFisherInference.pdf The emitted particles are assigned a weight so that the detected particles can be reweighted to an isotropic emission distribution instead of a vMF distribution. For details, see PoS (ICRC2019) 447.
