Resolution settings are used for the differentiation of adjacent peaks (spectra) and m/z values (calculations). Since Mass Frontier only processes centroid spectra, the differentiation is defined here as the spacing between resolved peaks (spectra) or as the smallest difference in m/z values that is distinguished (calculations). No additional parameters, such as peak width, are taken into account.

Precision refers to m/z values and is defined here as the position of the last digit relative to the decimal point that is displayed. Precision settings are only used for the display of m/z values and peak positions on the m/z scale. In contrast to resolution, precision settings are ignored in all calculations as the highest possible precision is always used. To assure the correct display of m/z values, the precision must be set to the same or a higher order than the resolution.
