XmlmmCIF equivalent: refine_ls_restr_type Data items in the REFINE_LS_RESTR_TYPE category record details about the restraints types used in the least-squares refinement. XmlmmCIF equivalent: refine_ls_restr_type/distance_cutoff_high The upper limit in angstroms of the distance range applied to the current restraint type. XmlmmCIF equivalent: refine_ls_restr_type/distance_cutoff_low The lower limit in angstroms of the distance range applied to the current restraint type. XmlmmCIF equivalent: refine_ls_restr_type/type This data item is a pointer to _refine_ls_restr.type in the REFINE_LS_RESTR category.
