Ufiles

Abstract
Ufiles are a simple file format standard for the exchange of single precision floating point scientific data. The Ufiles standard has enjoyed and continues to enjoy wide use in the plasma physics / fusion research community. Ufiles software implements the standard; this software was the backbone of diagnostic data analysis on the TFTR tokamak from 1983 to 1997. Ufiles come in four organizations: 0d, 1d, 2d, and 3d. All Ufiles contain a keyword indexed list of scalar values, 0d Ufiles contain only this list; for 1d, 2d, and 3d Ufiles the scalar list can have zero length. 1d Ufiles contain a gridded numeric representation of a 1d function of the form f(x), with numeric data, labeling, and physical units labeling for the function data and the x axis data. 2d Ufiles contain a numeric representation of f(x,y) with similar labeling. 3d Ufiles contain a numeric representation of f(x,y,z), again with similar labeling. A rich set of automatable interactive fortran-77 utility programs are available for the display and manipulation of Ufiles data. Ufiles come in several format variants, including: ascii, network-portable compressed binary, NetCDF, and HDF.
