Detailed Description

template<unsigned int MaxGaus = 10, unsigned int CutOff = 5>
class hit::CompiledTruncatedGausFitCache< MaxGaus, CutOff >

A set of TF1 linear sum of truncated Gaussians.

Template Parameters

MaxGaus	the maximum number of Gaussians in the stored functions
CutOff	number of sigmas beyond which the function evaluates as 0

This class stores a predefined number MaxGaus of TF1 from pre-compiled functions. Each function is the linear sum of truncated Gaussians, at most MaxGaus of them,
