I am trying to use FITDAT to convert the NASA polynomial coefficients into the fit Chemkin accepts for the thermodynamic data. The output file does not explain what is wrong. I appreciate your help.

My input file is:

DIAG 2               ! print table of data vs. resulting fit evaluation
TMAX 1000
POLY NASA      ! expects one set of NASA-format polynomial data

And the ioutput is:
