These are the Raw data used to generate the figures related to the publication:
"Evolution of the Fermi surface of the nematic superconductors FeSe1-xSx"
by A. I. Coldea, S. F. Blake, S. Kasahara, A. A. Haghighirad, M. D. Watson, 
W. Knafo, E. S. Choi, A. McCollam, P. Reiss, 
T. Yamashita, M. Bruma, S. Speller, Y. Matsuda, T. Wolf, T. Shibauchi, A. J. Schofield

The data given as ASCII files and a PDF for each figure is attached.
These data are generated by performing transport measurements in high magnetic fields
up to 45T at different low temperatures down to 0.35K
at the NHMFL in Tallahassee, Florida. Data were also collected up to 33T
at HMFL in Nijmegen.

Quantum oscillations are estimated by subtracting a high order polynomial from the raw data
and dividing to the original signal. Fast Fourier transform (FFT) using Hanning windowing are used
to extract the values of different frequencies. Masses are extracted from the temperature
dependence of the FFT amplitudes.

The Fermi surfaces were generated using Wien2K (http://susi.theochem.tuwien.ac.at/) 
and the input files are FeSe.struct and FeS.struct. 
The Fermi surfaces are plotted in Matlab and png files are attached.
