Removes rayleigh scattering with optional interpolation

Will remove both first and second order rayleigh scattering with the option to interpolate the removed area. Also makes note that the correction was made in an optional text file.

Usage

rayleigh(
  eem,
  rayleigh_mask = c(20, 10, 10, 10),
  rayleigh_width = "auto",
  rayleigh_interp = c(F, F),
  process_file = NULL,
  verbose = F
)

Arguments

eem

an object of class eemlist

rayleigh_mask

optional if auto width method is used, a vector of length 4 specifying the width of the rayleigh line to cut, numbers 1:2 are width above and below first order line, numbers 3:4 are width above and below second order line

rayleigh_width

either "auto" or "manual", if auto is chosen cutting widths will be found using the 'find_cut_width' function

rayleigh_interp

a vector of length two, either T or F, specifying whether the first and second order lines should be interpolated, the first position refers to the first order line, the way the code is written you cannot interpolate the first order line and not the second

process_file

a file path to a .txt file, used to track processing changes to EEMs

verbose

a logical, if TRUE will print out widths used to mask via the auto width method
