UVA_PAR: Calculate UVA:PAR photon ratio from spectral irradiance.

Description

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

Usage

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

Value

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

Arguments

spct

an object of class "source.spct"

std

select which definition of UVA should be used, defaults to "ISO"

use.cached.mult

logical indicating whether multiplier values should be cached between calls

use.hinges
