This is an example of the minimum input required to fit JANAF-format data, which is at least five columns consisting of temperature (K), and species properties C
p
(J/mole-K), 
(J/mole-K), 
(J/mole-K), and H
(T) - H
(298) (kJ/mole). Defaults SPEC=OH, PHAS=G , and ELEM
are obtained from the CODE
line, TMIN=300, TMAX=6000
are the first and last positive data points greater than 298, and H
(298) (kJ/mole) is the column 6 value at T=298.15, but keywords may be used to supersede the defaults.
