  The _chemical_formula_sum value was taken from the paper. The Z
  value was calculated from the cell contents to match the summary
  formula provided in the paper. The formula weight was recalculated
  from the new summary formula using atomic weights from
  http://www.webelements.com/. Old values are available in the
  _cod_original_* data items.
