Lorentzian Peak

This fit model is suited to fit resonances with a Lorentzian lineshape. For instance, this is the case if the resolution is limited the lifetime of the excitation, rather than by external noise.

Parameters:

  • y_0: offset in y direction
  • x_center: center of the peak
  • A: area of the peak
    • Height = 2 A/(Pi w)
  • w: width of the resonance
