erythema {photobiologyWavebands}

Constructor of erythema-weighted waveband

Description

Erythema BSWF (1998 update)

Usage

erythema(std = "CIE98", norm = 298, w.low = 250, w.high = 400)

CIE(norm = 298, w.low = 250, w.high = 400)

Arguments

std

a character string, currently only "CIE98" supported.

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

The erythema BSWF from CIE is specified by a mathematical formula, and this is used directly in the definition of the returned waveband.

Standard DIN 5031-10:2018-03 defines BSWF er as a table of interpolated values derived from CIE's definition from 1998. So, the values computed using this R package do not necessarily exactly match those according to DIN 5031-10:2018-03. The range of wavelengths used, 250 to 400 nm, does agree, with those in the standard.
