This function deletes two regions that are not related to fluorescence emission:
(1) regions where emission wavelength is shorten than excitation light,
(2) scattering rays and their second, third and forth order lights.
Usage
delScattering(EEM, rep = 0, first = 30, second = 40, third = 40, forth = 40)
Arguments
EEM
A list containing EEM data as created by readEEM function.
rep
(optional) Regions to be deleted are to be replaced with rep: 0 or NA
first
(optional) Width of region to be deleted for first order scattering rays [nm]
second
(optional) Width of region to be deleted for second order scattering rays [nm]
third
(optional) Width of region to be deleted for third order scattering rays [nm]
forth
(optional) Width of region to be deleted for forth order scattering rays [nm]
Value
A list similar to input EEM is returned but with all scattering rays deleted.
