   The number of reflections that satisfy the resolution limits
   established by _refine_ls_shell.d_res_high and
   _refine_ls_shell.d_res_low and the observation limit
   established by _reflns.observed_criterion, and that were used
   as the test reflections (i.e. were excluded from the refinement)
   when the refinement included the calculation of a 'free'
   R factor, expressed as a percentage of the number of
   geometrically observable reflections that satisfy the
   reflection limits.
