Dedicated optimised inversion of range-energy function for KVedaLoss.

We generate a TGraph of particle energy as a function of range from the VEDALOSS tables, and then use a TSpline3 interpolation in order to calculate rapidly the particle energy for any range value.

Definition at line 32 of file KVedaLossInverseRangeFunction.h.

◆ KVedaLossInverseRangeFunction() [2/2]

KVedaLossInverseRangeFunction::KVedaLossInverseRangeFunction	(	TF1 *	range_func,
		Int_t	A,
		Double_t	riso,
		Int_t	ninter = `50`
	)

Initialise from VEDALOSS range function object

Parameters

A	is mass of ion used in call to KVedaLossMaterial::GetRangeFunction
riso	is value corresponding to previous call to KVedaLossMaterial::GetRangeFunction
ninter	number of points in graph used for interpolation

We make a graph from 0.01 MeV/nucleon to EMAX.

We divide the calculated range by the current value of riso, thereby effectively ensuring that we always calculate range values corresponding to riso=1
