Re: [mesa-users] solar calibration with Asplund abundances

[Bill P. <pa...@ki...>]

Hi,

You might want to create an OP opacity table for the Asplund abundances.    
The mesa one is OPAL and I believe Aldo used OP for his work.

Note that there have been problems with the OP generated tables including a few NaN's at the table edge for low R.   But I think you can safely remove those by doing "interpolation by eye" to edit the text file.

If you get the table from the OP website, then I can do the mesa kap preprocessing to make the mesa format table.

Or perhaps someone out there has already done this?
