!The fluid files contain general information about the fluid in the first 15 to 20 lines, followed by sections for the
! equations of state, transport equations, and auxiliary equations. Equations of state are listed first. The NIST recommended
! equations begin with a hash mark (#). The secondary equations begin with the @ symbol. These symbols can be swapped to
! select a secondary equation as primary and the primary as secondary. The equation of state section also contains auxiliary
! equations for the ideal gas heat capacity or ideal gas Helmholtz energy. Below the equations of state (both primary and
! secondary) are the transport equations, first viscosity and then thermal conductivity. These are then followed by the
! secondary equations if available. The transport section also contains auxiliary equations required to calculate either the
! dilute gas state or the critical enhancement. At the end of the file are additional but not necessary auxiliary equations,
! including simple equations for the vapor pressure, saturated liquid and vapor densities, melting line (for some fluids), and
! sublimation line (for even fewer fluids). This section also contains the equations for dielectric constant and surface
! tension if available. The sections are divided by different symbols (these being _-+=^*~) to aid the eye in locating a
! particular section. Secondary equations are indented 10 spaces to avoid confusion with the NIST recommended equations. The
! end of the fluid file is marked with @END. Anything below that is ignored.

?The uncertainty in liquid density is 0.1% to 0.2% from 260 K to 370 K at
? pressures up to 3 MPa. No data are available below 260 K or at higher pressures.
? Above 370 K, the uncertainty remains small for liquid like states, and increases
? to 0.6% at temperatures above the critical point. Uncertainties are higher in
? the near critical region. In the vapor region, most data are represented to
? within 0.2% in density, except the experimental data for one isochore that
? appear to be wrong. The uncertainty in speed of sound is 0.03% in the vapor
? phase. In the liquid phase at 1 atm the uncertainty is 0.1% between 278 K and
? 298 K. States close to but outside this region will have similar uncertainties.
? The uncertainty in vapor pressure is 0.2% above 300 K. The uncertainty in heat
? capacities is estimated to be 2% or less.
