This data represent a snapshot, or instant in time, from the cosmology simulation. This snapshot was taken at a redshift of 2.75, which is 2.3 billion years after the Big Bang. At this point, the simulation had created 77,132 grids and 8 galaxy clusters with masses of at least 10^14 solar masses. The primary contents are the parameter files, hierarchy file (description of grid sizes and spatial locations), and grid data. For a complete description of the contents, refer to the Scope and Contents note for the collection. In the Derived Data subcomponent, there are text, binary, and images files representing halo properties and the projections of various physical fields.

"Data at Redshift=2.75 (RD0010)." From: Rick Wagner, Eric J. Hallman, Brian W. O'Shea, Jack O. Burns, Michael L. Norman, Robert Harkness, and Geoffrey So. "The Santa Fe Light Cone Simulation research project files." UC San Diego Research Cyberinfrastructure Data Curation. (Data version 1.0, published 2013; http://dx.doi.org/10.6075/W7154F0Q)
Technical Requirements:The parameter files are plain text, and can be accessed using a text editor or web browser. The complete snapshot is contained in an archive file in the <a href="http://en.wikipedia.org/wiki/Tar_%28file_format%29">tar file format</a>. Within the archive, the parameter and manifest file are plain text, while the grid files are binary files in the <a href="http://www.hdfgroup.org/HDF5/"HDF5 format</a>. Accessing the grid files requires either the HDF5 libraries or utilities. N.B: This only provides access to raw values; an additional layer is required to build the Enzo data model (e.g., YT).
