Dataset contains raw xy csv files for each individual plot/trace, where present, in all figures from both the main text and supporting information. Data takes the form: x1, y1 x2, y2 ... ... xn, yn Data has been organised into separate folders corresponding to individual sub-figures (figure 1a, figure 1b etc). Filenames correspond approximately to legend labels. Full description of each dataset can be found in figure captions and surrounding text.
