Notes. Near the pixel p0, the difference between two pixels corresponds to ~0.03 × 10−3m0 u q−1 in terms of mass-per-charge ratio in HR. As the HR resolution is >3000 at 1% peakheight, ion species should be separated by at least 10 pixels or ~ 0.33 × 10−3m0 to be resolved if the countsdo not exceed 100 times the noise level, the mass-per-charge separation has to be higher otherwise. First column: commanded mass-per-charge ratio m0 to which ions belong. Second column: algebraic mass-per-charge shift with respect to m0. Third column: the ion species.
