Category Description

               Data items in the REFINE_HIST category record details about the
               steps during the refinement of the structure.
               These data items are not meant to be as thorough a description
               of the refinement as is provided for the final model in other
               categories; rather, these data items provide a mechanism for
               sketching out the progress of the refinement, supported by a
               small set of representative statistics.
