root_database
*************
This is the :ref:`glossary@root_database` .
It must exist when this routine is called.

fit_database
************
This is a :ref:`glossary@fit_database` that
can be used to fit the root node.
The directory where the *fit_database* will be located must exist
when this routine is called.
This database is created as follows:

#. Copy the root node database to the fit node database.

#. Drop all of the constant tables from the fit node database; see
   :ref:`module@at_cascade.constant_table_list` .

#. Change the fit node database option table so that is uses the
   root node database for all the constant tables; i.e.,
   set the other_database and other_input_table options to do this.

#. Create an empty log table in the fit node database.
