Description Usage Arguments Value Note See Also Examples
Energy irradiance ratio between two wavebands for a radiation spectrum.
1 2 3 4 5 6 7 8 9 10 |
w.length |
numeric vector of wavelengths (nm). |
s.irrad |
numeric vector of spectral (energy) irradiances (W m-2 nm-1). |
w.band.num |
waveband object used to compute the numerator of the ratio. |
w.band.denom |
waveband object used to compute the denominator of the ratio. |
unit.in |
character Allowed values "energy", and "photon", or its alias "quantum". |
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. |
a single numeric value giving the unitless ratio.
The default for both w.band
parameters is a waveband covering
the whole range of w.length
