Peak shape determination of Bruker RapifleX MALDI-TOF spectral peaks. (a) Raw sample data (black stars) and peak fit to an asymmetric (blue-solid) and symmetric (red-dashed) Gaussian. Fit error is shown by the dotted lines. (b) Peak shape parameters as a function of m/z. Overall fitted trend is shown with solid lines and the linear (dashed) and quadratic (dotted) piecewise portions for ${\mathsf{\sigma }}_L$ and ${\mathsf{\sigma }}_R$ of the fits are extended past the trend range for reader visibility.
