In photobiologyPlants: Plant Photobiology Related Functions and Data

Calculate UV:PAR photon ratio from spectral irradiance.

Description

This function returns the UV:PAR photon ratio of a light source spectrum.

Usage

UV_PAR(spct, std = "ISO", use.cached.mult = FALSE, use.hinges = TRUE)

Arguments

spct	an object of class "source.spct".
std	select which definition of UV should be used, defaults to "ISO".
use.cached.mult	logical indicating whether multiplier values should be cached between calls.
use.hinges	logical indicating whether to use hinges to reduce interpolation errors.

Value

a single numeric dimensionless value giving the UV:PAR photon ratio, with name attribute set to the name of the wavebands, with "(q:q)" appended.
