Function to apply spectral efficiency correction to RLum.Data.Spectrum S4 class objects

The function allows spectral efficiency corrections for RLum.Data.Spectrum S4 class objects

Usage

apply_EfficiencyCorrection(object, spectral.efficiency)

Arguments

object: RLum.Data.Spectrum or RLum.Analysis (required): S4 object of class RLum.Data.Spectrum, RLum.Analysisor a list of such objects. Other objects in the list are skipped.
spectral.efficiency: data.frame (required): Data set containing wavelengths (x-column) and relative spectral response values (y-column) (values between 0 and 1). The provided data will be used to correct all spectra if object is a list

Value

Returns same object as provided as input

Details

The efficiency correction is based on a spectral response dataset provided by the user. Usually the data set for the quantum efficiency is of lower resolution and values are interpolated for the required spectral resolution using the function stats::approx

If the energy calibration differs for both data set NA values are produces that will be removed from the matrix.

Note

Please note that the spectral efficiency data from the camera alone may not sufficiently correct for spectral efficiency of the entire optical system (e.g., spectrometer, camera ...).
