Conditions never met adapt_grid()

[avigan]

Looking at the adapt_grid.py module I think there are some problems with conditions that can never be met:

https://github.com/exoAtmospheres/ForMoSA/blob/aa43396a094aff925af8456eff2d7d4d46083156/ForMoSA/adapt/adapt_grid.py#L97C1-L98C1

nan_mod_ind = ~np.isnan(model_to_adapt)
if len(np.where(nan_mod_ind is False)[0]) == 0:
    mod_spectro, mod_photo = adapt_model(global_params, wav_mod_nativ, model_to_adapt, res_mod_obs_merge, obs_name=obs_name, indobs=indobs)

Even if there are many NaN in model_to_adapt, the condition len(np.where(nan_mod_ind is False)[0]) == 0 will always be True. This is because nan_mod_ind is an ndarray so it will never be False. The test is False is extremely specific: it means that nan_mod_ind must be the object False.

Proposed solution:

nan_mod_ind = np.isnan(model_to_adapt)
if np.any(nan_mod_ind):
    ... # print error message
else:
    mod_spectro, mod_photo = adapt_model(global_params, wav_mod_nativ, model_to_adapt, res_mod_obs_merge, obs_name=obs_name, indobs=indobs)

np.any(nan_mod_ind) check if any of the elements in nan_mod_ind is True.
