energy_irradiance: Calculate (energy) irradiance from spectral irradiance

Description

Energy irradiance for a waveband from a radiation spectrum, optionally applying a "biological spectral weighting function" or BSWF.

Usage

energy_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))

Arguments

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

a character Allowed values "photon" or "energy", default is "energy".

check.spectrum

logical Flag indicating whether to sanity check input data, default is TRUE.

use.cached.mult

logical Flag indicating 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.

Value

A single numeric value with no change in scale factor: [W m-2 nm-1] -> [W m-2].
