SpringerImages - Simulation of the peak picking precision achieved with the new GAPRO peak picker. The standard deviation of the difference between the real peak position and the picked peak position in units of the digital resolution (digital points, pts), Δπ, is plotted versus the ratio of signal intensity and spectral noise (S/N). Each data point (open squares) represents an average over 100,000 simulated peak picking events (see text). The four data sets differ in the assumed widths of the resonance lines in digital points: solid line 21 pts, dashed line 11 pts, dotted line 6 pts, dashed-dotted dashed line 1 pt

1 c, 2 ), and therefore we recommend to use 1 digital point as the input value for Δ ν_min and r_min (Table 1 ).

2 represents the standard deviation of the precision calculated from 100,000 such peak picking events..
