[Mesa-users] [EXT] Trying to add new output data

[Mathieu Renzo]

Hi Ishaan,

That error suggest those parameters have been removed (but maybe are 
left in the `profile_columns.list` by mistake).
I think you are using the right approach, but maybe you're trying to use 
`data_for_extra_history_columns` - which as you say is for "global" 
properties of the star, while you probably want to work on 
`data_for_extra_profile_columns` (just below at your link), which is for 
spatial distribution of  quantities as a function of mesh point. Your 
functions to calculate the quantities you want should go there if you 
want their internal distribution.

Cheers,
Mathieu
