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).
