the phase shift is dependent on the time the wave travels in the plasma until it gets to the reflecting layer... along the way, it meets layers which have a non-zero index of refraction which must be accounted for... and these are not always in the same position... or else, why have such a diagnostic at all?
That sounds difficult... is that is why you integrate over those frequencies in your formula? To account for all the stuff happening in between? Or is that thinking too naively...
