SORTAV Absorption correction

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 more information visit the service web site at: http://www.soton.ac.uk/~xservice/
