If you run aviary convert_engine -f GASP CFM_56_7B27.eng, you will get RuntimeWarning: divide by zero encountered. This is because this GASP engine file has the following table:
Aviary uses 3d-lagrange3 interpolation which requires at least four points.
We can either automatically switch to linear interpolation or have a pre-process to CFM_56_7B27.eng by adding another point (say Mach 0.5) to it along with each T4/T2 value.
BTW the format for the data is F10.4 to read off the values. a lot of the more recent engine decks use data to one decimal point for the data. Really does not make a lot of sense to know the values of the thrust to the fourth decimal point.
