Even when you have a well-converged simulation, a temperature profile from *Exo-REM* will always have some oscillations in it. Most of the time, they will be insignificant. Sometimes they can be more important. However, most of the time this should not be worrying, and it can be very hard to get rid of them. Here is a list of things you can do to improve your profile:

1. Decrease `retrieval_flux_error_bottom` and `retrieval_flux_error_top` down to roughly 1e-15 (fortran double precsion). Decrease a lot `weight_apriori` (consider 1e-15 as a high value). Set `retrieval_tolerance = 0`. Increase a lot `n_iterations` (50, or more) and `n_non_adiabatic_iterations` (20, or more).
