Check e.g.Fig 5 leaf 68 (no solvent).
Top right tables of figures give the ranges, also marked on the bottom of the chart. "95.4% probability" : 1396-1457 (fits with range marked on bottom of chart). The difference is 61, which is +/- 2 = 4 sigma. So sigma = 15. Roughly!
There seems to be a bit of weighting or rounding going on and I don't know the meaning of the "93.8%" in brackets so simple calculations are not exact. Maybe some skew or kurtosis in the graph too.
