UVA_UV: 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.
