Energy or photon irradiance for one or more wavebands of a radiation spectrum.
irradiance(
w.length,
s.irrad,
w.band = NULL,
unit.out = NULL,
unit.in = "energy",
check.spectrum = TRUE,
use.cached.mult = FALSE,
use.hinges = getOption("photobiology.use.hinges", default = NULL)
)
A single numeric value or a vector of numeric values with no change in scale factor: [\(mol\,s^{-1}\,sm^{-2}\,nm^{-1}\)] yields [\(mol\,s^{-1}\,sm^{-2}\)]
numeric Vector of wavelength [\(nm\)].
numeric vector of spectral (energy) irradiances [\(W\,m^{-2}\,nm^{-1}\)].
waveband or list of waveband objects The waveband(s) determine the region(s) of the spectrum that are summarized.
character Allowed values "energy"
, and
"photon"
, or its alias "quantum"
.
logical Flag indicating whether to sanity check input
data, default is TRUE
.
logical Flag indicating whether multiplier values should be cached between calls.
logical Flag indicating whether to insert "hinges" into the spectral data before integration so as to reduce interpolation errors at the boundaries of the wavebands.
