fitting.displor(x, A, B, x0, dx)¶

A dispersive Lorentzian without baseline / offset.

Parameters:	x (array) – x-values. A (float) – Intensity of real part. B (float) – Intensity of dispersive part. x0 (float) – Center along x-axis. dx (float) – FWHM.
Returns:	$f(x) = \frac{A + 2 B (x - x_0) / \Delta x}{1.0 + 4 (x - x0)^2 / \Delta x^2}$ .
