fluspect: fluspect

In fluspect: Fluspect-B

Description

fluspect calculates reflectance and transmittance spectra of a leaf using FLUSPECT-B, plus four excitation-fluorescence matrices

Usage

fluspect(leafbio, spectral = define.bands(), optipar = NULL)

Arguments

leafbio	Data Frame. It contains: Cab, Cca, Cw, Cdm, Cs, N, fqe
spectral	List. (Optional) A spectral object created with define.bands. A default spectral object is used if the user does not indicate any.
optipar	Data Frame. (Optional) It contains: nr, Kdm, Kab, Kca, Kw, Ks, phiI, phiII. A default optipar object is used if the user does not indicate any.

Value

a list which contains:

• refl (reflectance)

• tran (transmittance)

• Mb (backward scattering fluorescence matrix, I for PSI and II for PSII)

• Mf (forward scattering fluorescence matrix, I for PSI and II for PSII)
