Constructor of GPAS (Micheletti's formulation) weighted waveband

Generalized Plant Action BSWF of Caldwell [1] as formulated by Micheletti et al. [2]

Usage

GEN_M(norm = 300, w.low = 275, w.high = 313.3)

Arguments

norm

normalization wavelength (nm)

w.low

short-end boundary wavelength (nm)

w.high

long-end boundary wavelength (nm)

Value

a waveband object wavelength defining wavelength range, weighting function and normalization wavelength.

Note

In the original publication [2] describing the formulation, the long-end wavelength boundary is specified as 313.3 nm. This is the default used here. However, in some cases it is of interest to vary this limit in sensitivity analyses. The effect on the RAF and doses of changing this boundary is substantial, and has been analysed by Micheletti et al. [3].
