This data provides the data points of Figures 1-5 from the paper "A Closed-Form Expression for the Gaussian Noise Model in the Presence of Inter-Channel Stimulated Raman Scattering Extended for Arbitrary Loss and Fibre Length", submitted to the Journal of Lightwave Technology (JLT). Each figure is in separate folders. For each figure, you will find the corresponding TXT file used to plot the data of the figures in the paper. The TXT files are made of columns, where each column represents one of the curves in the graphs. The titles of each column are self-explanatory so you can easily related the column with the graphs in the paper. Please, read the file "read me" if you find it in the relevant figure folder.
