Peak Functions¶
Symmetric Peak Functions¶
These peak functions exhibit a symmetry about the peak center. FWHM is the full width at half-maximum, the width of the peak at 50% of its amplitude.
Complementary Error Function Peak
Gauss-Lorentzian Cross Product
Symmetric Double Sigmoidal (SDS)
Symmetric Double Gaussian Cumulative (SDC)
Asymmetric Peak Functions¶
These peak functions exhibit an asymmetry about the peak center. FWHM is the full width at half-maximum, the width of the peak at 50% of its amplitude. When a function can model both left and right shifted peaks, both types will be illustrated in the accompanying graph.
