fitting.lorOscRe(w, A, w0, dw)¶

Real part of a Lorentz oscillator model for the dielectric function.

Parameters:	w (array) – Angular frequency. A (float) – Amplitude. w0 (float) – Resonance frequency. dw (float) – Damping rate.
Returns:	$f(w) = 1 + \frac{A (\omega_0^2 - \omega^2)}{ (\omega_0^2 - \omega^2)^2 + \Delta \omega^2 \omega^2 }$ .
