This document outlines how the data in this repository is structured. The software required to run the files in the repository is: Matlab The folders in the repository are structured as follows. 1) The folder "Figures" contains the Matlab plots that have been used for the figures in the paper. All Matlab .fig files can be opened with Matlab and the curves copied then elsewhere. The data from each of the figures can also be extracted from the plots by accessing the object fields directly. See the Mathworks help pages for more details. For example, see here: https://uk.mathworks.com/matlabcentral/answers/2951-extracting-data-series-from-fig-file 2) The folder "Figures" also contains edited .pdf versions of the Matlab figures, which are the ones printed in the paper.
