N.B. The scaling summary is redundant as outliers are treated during
the absorption correction using SORTAV. The quoted data completeness is
for the stated resolution ranges, and the Overall R-merge is that before
the absorption correction. The SORTAV transmission factors are based on
a crude approximation and the expected formula (not always correct!). For
