Multiple file types are included. These are: *.csv files These contain comma separated values with header information, and may be opened with a text editor. m*.ovf files These are normalised magnetisation files from MuMax3, and may be opened in MuMax3, Muview, or any compatible OVF (OOMMF Vector Field Format) reader. https://mumax.github.io/ https://github.com/grahamrow/Muview2 *.npz files These are compressed NumPy array(s), and may be opened in Python or any compatible reader. https://www.python.org/ https://numpy.org/ *_endstates.npz contain arrays of the end-state "strengths": ['ss', 'ls', 'cs'], where the leading letter specifies the end-state type as defined in the manuscript. The labels `h' and `v' used in the files correspond to `horizontal' and `vertical' islands, as defined in the manuscript. The reduced magnetisations in the y- and x-directions for the data in figure 11 is in npz format, under the label 'myx'. Details of the simulation conditions, experimental procedure, and data processing are described in the manuscript.
