calc_multipliers: Spectral weights

Description

Calculate multipliers for selecting a range of wavelengths and optionally applying a biological spectral weighting function (BSWF) and wavelength normalization. This function returns numeric multipliers that can be used to select a waveband and apply a weight.

Usage

calc_multipliers(w.length, w.band, unit.out = "energy", unit.in = "energy",
  use.cached.mult = FALSE, fill = 0)

Arguments

w.length

numeric Vector of wavelengths (nm)

w.band

waveband

unit.out

character A string: "photon" or "energy", default is "energy"

unit.in

character A string: "photon" or "energy", default is "energy"

use.cached.mult

logical Flag indicating whether multiplier values should be cached between calls

fill

numeric If fill==NA then values returned for wavelengths outside the range of the waveband are set to NA

Value

• a numeric array of multipliers of the same length as w.length

Examples

with(sun.data, calc_multipliers(w.length, new_waveband(400,700),"photon"))
