_cod_error_description
;
 In the table of atomic positions and displacement factors of the original
 publication RE1, RE2, RE3, RE4 disorder sites are defined. In the upstream
 CIF these sites are represented by providing several atom entries with same
 coordinates, but different occupancies (for example, the RE1 site is
 represented by the Ce1, Nd1, La1, Dy1, Pr1, Gd1, Sm1, Er1 atom entries).
 However, such representation results in atom bumps (atoms that are too close
 to each other).
