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. Conversion between energy- and photon-based units. Wavelength
interpolation. Astronomical calculations related solar angles and day
length. Colours and vision.
