 - ``model_subspace_indices``: The indices that locate this model in its model subspace.
 - ``criteria``: The value of the criterion by which model selection was performed, at least. Optionally, other criterion values too.
 - ``model_hash``: The model hash, generated by the PEtab Select library. The format is ``[MODEL_SUBSPACE_ID]-[MODEL_SUBSPACE_INDICES_HASH]``. If all parameters are in the model are defined like ``0;estimate``, then the hash is a string of ``1`` and ``0``, for parameters that are estimated or not, respectively.
-- ``model_subspace_petab_yaml``: Same as in model space files (see ``petab_yaml``).
+- ``model_subspace_petab_yaml``: Same as in model space files.
 - ``estimated_parameters``: Parameter estimates, including all estimated parameters that are not in the model selection problem; i.e., parameters that are set to be estimated in the model subspace PEtab problem but don't appear in the column header of the model space file.
 - ``iteration``: The iteration of model selection in which this model appeared.
 - ``model_id``: The model ID.
