Synthetic fluorescence excitation-emission matrices and absorbance spectra
Description
This dataset consists of twelve fluorescence and absorbance spectra simulated from three trilinear components, with scattering signal added and divided by a correction factor to simulate inner filter effect.
Usage
data("feems")
Format
- feems
-
A named list of 12
feem
objects containing fluorescence data measured with excitation wavelengths between230
nm and350
nm (with a step of2
nm) and emission wavelengths between240
nm and435
(with a step of5
nm). - cube
-
A 12-sample
feemcube
object consisting of of 32 by 10 FEEMs measured at the same wavelength range as above with inner filter effect corrected. - absorp
-
A 12-element named list containing absorbance spectra measured between
230
and450
nm in1
cm cells. Each element of the list is a two-column matrix. The first column contains the wavelengths and the second column contains the absorbance values.
