Fig. 2 Data are presented in a *.csv file, column 1 is the temperature, column 2 is the real part of the susceptibility and column 3 is the imaginary part of the susceptibility. Fig. 3 Images are archived as *.txt (raw data) and *.dat (raw data) files composed of 128x128 pixel matrices containing values of the measured magnetic field in G. Filenames indicate mesa shape, rotation angle and either measurement field in G or measurement temperature in K. Fig. 4 Images are archived as *.dat (raw data) files composed of 128x128 pixel matrices containing values of the measured magnetic field in G. Filenames indicate mesa shape and rotation angle. Fig. 5 Measured linescans are presented in a *.csv file. Square0 (cols 1,2); Square22.5 (cols 3,4); Square45 (cols 5,6); Triangle (cols 7,8); Pentagon (cols 9,10); Octagon (cols 11,12). Calculated edge field profile is saved as *.dat (comma delimited) file. Fig. 6 Images are archived as *.txt (raw data) files composed of 128x128 pixel matrices containing values of the measured magnetic field in G. Filenames indicate measurement field in G and measurement temperature in K. Fig.7 (a) Images are archived as *.txt (raw data) files composed of 128x128 pixel matrices containing values of the measured magnetic field in G. Filenames indicate measurement field in G and measurement temperature in K. (b) Data in plot of rms magnetic roughness versus cooling field are presented in a *.csv file. T=300mK (cols 1,2); T=600mK (cols 4,5); T=900mK (cols 7,8). Fig. 8 Images are archived as *.dat (raw data) files composed of 128x128 pixel matrices containing values of the measured magnetic field in G. Filenames indicate mesa shape, rotation angle, measurement field in G and measurement temperature in K. Fig. 9 Linescans are presented in a *.csv file. Measured linescan (cols 1,2); calculated fit (cols 3,4). Inset image archived as *.txt (raw data) file composed of 128x128 pixel matrices containing values of the measured magnetic field in G.
