Data from "Measurement of the superfluid fraction of a supersolid by Josephson effect'

Here we store the data shown in the main text and methods of the manuscript "Measurement of the superfluid fraction of a supersolid by Josephson effect". The data are organized in .dat files with the following scheme: 

X axis    Y axis    Y axis error (if available)     X axis error (if available)

The name of the files refer to the figure number in the paper. If more datasets are plotted in the same figure, the name of the file contains additional information. For example, the file 'FigED5b_Z.dat' contains the data in Extended Data Fig. 5 for the imbalance Z.
