Member Function Documentation

virtual TF1* reco_tool::BaselinedGausFitCache::CreateFunction ( size_t  nFunc ) const

inlineprotectedvirtual

Creates and returns the function with specified number of Gaussians.

The formula is gaus(0) + gaus(3) + ... + gaus(3*(nFunc-1)) + [nFunc*3].

Reimplemented from hit::GausFitCache.

Definition at line 41 of file PeakFitterGaussian_tool.cc.
