enginpower is on a distinguished road
I want to run a simulation with butane gas.

I need to set the values of Janaf coefficients that I found from this discussion
Practically the value of Janaf cefficient are here,
but it's not clear what are the values for the Janaf polynomial coefficients.

Could you help me to find High temperature Cp coefficients and Low temperature Cp coefficients?

Data of my interest should be these ones:

C4H10,n-butane    TRC w 1350,10/85. JPCRD v4 n4,1975,p859.
