#include <Nasa9PolyMultiTempRegion.h>
The NASA 9 polynomial parameterization for a single species encompassing multiple temperature regions.
The parameterization used in each temperature range is described in the documentation for class Nasa9Poly1.
These NASA representations may have multiple temperature regions through the use of this Nasa9PolyMultiTempRegion object, which uses multiple copies of the Nasa9Poly1 object to handle multiple temperature regions.
