Datasets for Benchmarking Floating-Point Compressors

Datasets are little-endian single- and double-precision IEEE 754 arrays, with the first dimension of the extent being the slowest dimension in the multidimensional array. Files are compressed using Zstandard.

astro_mhd and astro_pt simulations were performed separately with single- and double-precision arithmetic; the remaining single-precision datasets are simply truncated from their double-precision counterparts.
