Variables

constexpr size_t GSFConstants::alignment = vAlgs::alignmentForArray<256>()
 Alignment used for SIMD operations internally to GSF.

 The state is described by N Gaussian components The Beth Heitler Material effect are also described by M components.
constexpr int8_t GSFConstants::maxNumberofMatComponents = 6
 Maximum number of Gaussian components for the material effects description.
constexpr int8_t GSFConstants::polynomialCoefficients = 6
 Number of coefficients for the polynomials, parametrizing the mean,variace, weights of the Gaussian components describing the material effects.
