Seems okay then.
We got a reviewer comment on the Na to NaOH ratio at the magma ocean surface (2000 K). The reviewer used a gibbs free energy minimizer and recieved different results. This was also due to the reviewer running the minimizer at T = 2500 K, but using the old nasa polynomials was better in line with his results. I agree that using hte latest polynomials might be a better approach. Thanks for clarifying and attached you find a sheet where I checked the difference between Cp/R, H/RT, and S/R

It is actually from the updated new_nasa9.TXT. Have you checked how they differ? I wouldn't expect them to differ too much.
