Detailed Description

Sample with a charge-weighted gaussian.

Class for sampling a collection of AtHits in a spacial gaussian distribution around the reference hit where the hits are weighted by charge.

Member Function Documentation

PDF()

std::vector< double > AtWeightedGaussian::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)};

Returns

vector where each element is a different maginal pdf

Implements RandomSample::AtSample.
