In photobiologyPlants: Plant Photobiology Related Functions and Data

Calculate UVA:UV photon ratio from spectral irradiance.

Description

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

Usage

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

Arguments

spct	an object of class "source.spct"
std	select which definition of UVB and 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 nondimensional value giving the UVA:UV photon ratio, with name attribute set to the name of the wavebands, with "(q:q)" appended.
