Detailed Description

Sample AtHits in gaussian from reference.

Class for sampling a collection of AtHits in a spacial gaussian distribution around the reference hit.

std::vector< double > AtGaussian::PDF ( const AtHit & hit )

overrideprotectedvirtual

Computes the unnormalized marginal PDFs at the hit.

For example, a charge-weighted and spacial gaussian would looke like return {charge, gaussian_pdf(distance, sigma)};
