Hi all,

Could anyone tell me a book/paper/reference where to find the species polynomial coefficients required to calculate the absorptivity coefficient according to the "greyMeanAbsorptionEmission" model?

In other words, does anybody know where following coefficients come from?

************************************************** ****************************
CO2
{
Tcommon 300; //Common Temp
invTemp true; //Is the polynomio using inverse temperature.
Tlow 200; //Low Temp
Thigh 2500; //High Temp

loTcoeffs //coefss for T < Tcommon
(
0 // a0 +
0 // a1*T +
0 // a2*T^(+/-)2 +
0 // a3*T^(+/-)3 +
0 // a4*T^(+/-)4 +
0 // a5*T^(+/-)5 +
);
hiTcoeffs //coefss for T > Tcommon
(
18.741
-121.31e3
273.5e6
-194.05e9
56.31e12
-5.8169e15
);

}
************************************************** ****************************

Thanks
