Constructor & Destructor Documentation

Builder()

CaloSwPhimod_v2::Builder::Builder	(	const CxxUtils::Array< 3 > &	correction,
		const CxxUtils::Array< 1 > &	interp_barriers,
		int	degree,
		float	correction_coef,

	)

Constructor.

Constructor for energy interpolation table helper class.

Gets the correction information, the abs(eta) and phi at which the correction is being evaluated (in cal-local coordinates), and the number of absorbers.

Parameters

correction	The correction table.
interp_barriers	Allow breaking up the interpolation into independent regions.
degree	Interpolation degree.
correction_coef	Coefficient by which to scale the entire correction.
aeta	The absolute value of \(\eta\) at which the correction is being evaluated (in cal-local coordinates).
phi	The \(\phi\) at which the correction is being evaluated (in cal-local coordinates).
nabs	Number of absorbers in \(2\pi\).

Member Function Documentation

calculate()

float CaloSwPhimod_v2::Builder::calculate ( int  energy_ndx, bool &  good  ) const

virtual

Calculate the correction for tabulated energy ENERGY_NDX.

Calculate the correction for one tabulated energy index.

Parameters

energy_ndx	The tabulated energy index for which the correction should be calculated.
good[out]	Set to true if the calculation succeeds.

Implements CaloClusterCorrectionCommon::TableBuilder.
