node_table
**********
is a ``list`` of ``dict`` containing the node table for this cascade.

fit_node_id
***********
is the :ref:`create_job_table@job_table@fit_node_id` for this fit.

fit_split_reference_id
**********************
is the :ref:`create_job_table@job_table@split_reference_id` for this fit.
If this is an ``int`` ( ``None`` ),
the :ref:`option_all_table@split_covariate_name` does is (is not)
in the option_all table.

mulcov_freeze_table
*******************
is the :ref:`mulcov_freeze_table-name` for this cascade.

mulcov_freeze_dict
******************

keys
====
The keys in this dictionary is the
set of :ref:`mulcov_freeze_table@mulcov_id` for covariates
that should be frozen for jobs that are children of this fit.
In other words, if this fit job, and any parent of this fit job,
is in the mulcov_freeze table,
the corresponding *mulcov_id* is in *mulcov_freeze_dict* .

values
======
#. If this fit job is in the mulcov_freeze table with this *mulcov_id* ,
   *mulcov_freeze_dict* [ *mulcov_id* ] is 'posterior' .

#. If a parent of this fit job is in the mulcov_freeze table  with this
   *mulcov_id* , *mulcov_freeze_dict* [ *mulcov_id* ] is 'prior' .
