?\
?Note:  Marx et al. give a Helmholtz form for the ideal gas term; it
? has been converted to a Cp0 form, by the transform:\
?\
?   Cp0/R = (1 + a_3) + SUM{a_i*U_i*exp(U_i)/[1 - exp(U_i)]**2}\
?   where U_i = omega_i*T_n/T, T_n = Tcrit, \
?   and the a_i and omega_i are the original coefficients given by Marx\
