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!).
