Hi,

This was the inlist I used.


Thanks,

hi negan,

its difficult to assess with just a plot.

i'll echo rob's question from his 05sep2022 reply to your previous message

https://linkprotect.cudasvc.com/url?a=https%3a%2f%2flists.mesastar.org%2fpipermail%2fmesa-users%2f2022-September%2f014010.html&c=E,1,ELB0WHnXV9oAXwzBiRIfphYSayY5RdEEoAcM5q6u7iR_JT4P5PRa702pJ2Sw-1kQdlkZxxJhkEfDkaLyBHjkTPMVz40r7gX3noxsn6ZQOh7GrO-FXEqg-Cjp4g,,&typo=1

> Can you show your inlists?
