Data are provided in separate folders relating to the figures in the manuscript where possible.

All data provided in ASCII format. No specialised software is needed for plotting the data.
X-ray diffraction analysis is possible with the free software described in the manuscript.
All data files contain columns with independent variable, dependent variable and  errors of each where applicable. 

Column assignments in first line of each file. Units where applicable in second line of each file.
