DATASET NAME: NYX

DATASET OWNER’S NAME AND CONTACT: Sheng Di or Zarija, sdi1@anl.gov

ARRAY DIMENSION: 3D

Dimension sizes: 512x512x512

DATA NATURE (INTEGER or DECIMAL,…): CECIMAL
PHYSICAL DESCRIPTION OF THE DATASET: 
compressible cosmological hydrodynamics simulation code (Nyx): https://ccse.lbl.gov/Research/NYX/ 
The Nyx simulation data are post-analysis data composed of 3D arrays in space (such as dark matter density and temperature).

ENDIAN FORMAT: Little endian
PRECISION (DOUBLE, SINGLE): single-precsion

More description: 

Note: From a visualization perspective, we recommend compressing the two fields (dark matter density and baryon density) in the log domain, particularly because of their highly skewed data distributions: most values are close to zero, while the overall value ranges span many orders of magnitude. So, this dataset addresses this need.
