[Mesa-users] Custom color file

[Susmita Das]

Hi Aaron and Rob,
Thank you very much for your reply and sorry for my late reply.
I'm using mesa-r21.12.1.
Restricting to the sub-table with Av=0 indeed did away with the warning.
However, I still get the error of bad filter name (I used the filter names
in lowercase in the filter file as well as the history file). Once again,
it shows no error regarding gaia_rp but only with the other four filters.

I would be very grateful for your help.
Thank you
Susmita
