Photon irradiance
This function returns the photon irradiance for a given waveband of a radiation spectrum, optionally applies a BSWF.
photon_irradiance(
w.length,
s.irrad,
w.band = NULL,
unit.in = "energy",
check.spectrum = TRUE,
use.cached.mult = FALSE,
use.hinges = getOption("photobiology.use.hinges", default = NULL)
)w.length |
numeric vector of wavelength (nm). |
s.irrad |
numeric vector of spectral irradiances, by default as energy (W m-2 nm-1). |
w.band |
waveband. |
unit.in |
character Values recognized "photon" or "energy". |
check.spectrum |
logical Flag telling whether to sanity check input data, default is TRUE. |
use.cached.mult |
logical Flag telling whether multiplier values should be cached between calls. |
use.hinges |
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. |
A single numeric value with no change in scale factor: [mol s-1 m-2 nm-1] -> [mol s-1 m-2].
