These are a suite of 21cmfaster runs, which calculate the redshift of reionization of each cell in a comoving volume. The outputs are 512^3 resolution boxes representing a (400Mpc)^3 comoving volume of the universe. All were run with the same initial paramaters. There are 3 data subdirectories, each comtaining 33 realizations of the field: density_Lag/ - the Lagrangian density field scaled to z=0.0 density_Eul/ - the Eulerian density field at z=10.0 reionization/ - the redshift of reionization and 1 directory containing notebooks for visualization/ML purposes: notebooks/ Data format: The data is binary float32 format. Simply read in 512^3 float32's and reshape to an array of shape=(512, 512, 512).
