A.illuminant.spct

A dataset containing wavelengths at a 5 nm interval (300 nm to
 830 nm) and the corresponding spectral energy irradiance normalized to 1 at
 560 nm. Spectrum approximates typical, domestic, tungsten-filament lighting
 and 'corresponds' to a black body a 2856 K. CIE standard illuminant A is
 intended to represent typical, domestic, tungsten-filament lighting.
 Original data from CIE downloaded on 2024-11-30.

datasets

Definitions of classes, methods, operators and functions for use
in photobiology and radiation meteorology and climatology. Calculation of
effective (weighted) and not-weighted irradiances/doses, fluence rates,
transmittance, reflectance, absorptance, absorbance and diverse ratios and
other derived quantities from spectral data. Local maxima and minima: peaks,
valleys and spikes. Conversion between energy-and photon-based units.
Wavelength interpolation. Astronomical calculations related solar angles and
day length. Colours and vision. This package is part of the 'r4photobiology'
suite, Aphalo, P. J. (2015) <doi:10.19232/uv4pb.2015.1.14>.
