Non-converged (?) exo-rem models in current grid

[gabrielastro]

Plotting the models of the current exo-rem.tgz grid (from 2024-03-11), there are some suspicious non-monotonicities and some of my fits are getting stuck at the edge. For example (colour = flux):

• exo-rem_teff_1600_logg_4.0_feh_1.0_co_0.80 sticks out dramatically from the other C/O values:
  

• exo-rem_teff_1600_logg_3.5_feh_1.0_co_0.50 sticks out dramatically from the other C/O values:
  

These are just two examples and I have not looked systematically into this. (Let me know if I should!) I am looking forward to the new Exo-REM grids (#103) but in case you keep these older grids, it might be worth it to remove the offending models, which lead to spurious convergence, especially when at the grid edge. species interpolates over missing models, yes? Then I guess that removing them should work.

Thanks!
