PrIMe Thermodynamic Polynomials data records are associated with chemical species, and provide
polynomial fits to the thermodynamic properties. The records also include the reference state,
related enthalpy of formation and temperature range for which each of the polynomials is valid.
PrIMe schema currently recognizes NASA-7-coefficient and NASA-9-coefficient polynomials.
Unlimited number of thermodynamic polynomial records can be stored in each species data foder.
Thermodynamic polynomial records are designated by primeID identifier "thp", followed by a unique
8-digit sequence; for example: thp00001234. thp00000000 primeID is reserved for the record which
PrIMe Working Group on thermodynamic data has designated as the Best Current Value.
For every numerical value (except for the limits of the validity range)
uncertainty can be specified.
