fluspect
calculates reflectance and transmittance spectra of a leaf using FLUSPECT-B,
plus four excitation-fluorescence matrices
1 | fluspect(leafbio, spectral = define.bands(), optipar = NULL)
|
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. |

Original version in MatLab: github.com/Christiaanvandertol/Fluspect
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)
