Member Function Documentation

◆ PDF()

std::vector< double > AtUniform::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.

Definition at line 24 of file AtUniform.cxx.

◆ SampleHits()

std::vector< AtHit > AtUniform::SampleHits ( int  N)
overridevirtual

Sample hits (AtHit) from fHits.

Assumes fCDF is already setup and we are just using it.

Reimplemented from RandomSample::AtSample.

Definition at line 11 of file AtUniform.cxx.

◆ SetHitsToSample()

virtual void RandomSample::AtUniform::SetHitsToSample ( const std::vector< const AtHit * > &  hits)
inlineoverridevirtual

Implements RandomSample::AtSample.

Definition at line 19 of file AtUniform.h.
