This data repository folder contains various files associated with Savanna van Mesdag's PhD thesis. Each of these subfolders in the overall repository folder contains one README file, providing details about the contents of the subfolder. Each file (in each subfolders) refers to Chapters 3, 4, 5 or 6 in the thesis. While some files are present in more than one subfolder, each subfolder is self-contained, meaning that you can view the contents specific to just one chapter, allowing for easier and more straight-forward interpretation, rather than having files from more than one chapter 'jumbled up.' Files from each folder are described further in chapters S1, S2, S3 and S4 in the thesis. Please refer to both the relevant sections of the Supplementary Information chapters and the folder-specific README files before viewing (and possibly utilising) any of the individual files in this repository.
