Background
The correction of deviations in spectra measured with a spectrometer is often necessary in order to obtain accurate results. The classical approach for such a correction is based on a method by Stearns. However, we demonstrated in

that the Richardson-Lucy method can produce much better results. Therefore, PTB Working Group 8.42 has written a software implementation of an adapted Richardson-Lucy method with an automatic stopping rule. This software includes MATLAB code as well as a graphical user interface written in Python.

Usage
This software package actually consists of two independent packages: Matlab and Python implementation of the Richardson-Lucy method for 1D spectral deconvolution. Detailed instructions can be found in the respective folder.
