One is calculated from the str and the other from the dummy_str; the latter uses the elemental results from the first str but which could be from an XRF analysis. The two macros AW_Ce and AW_O are atomic weights for Ce and O respectively; these values come from the file isotopes.txt. This example could easily be extended to many elements. The denominator in Line 2 should probably correspond to the element with the highest weight percent.
