    Re: AP terminology

    You are pretty close, I am a theoretical and computational physicist (in the area of radiative properties of plasmas).  I have also been exposed to the field known as mathematical physics but decided a long time ago that I was not going to go in that direction.

    Your last question may be a tongue-in-cheek rhetorical one, but I'll try to answer it anyway... :-)   I'd say that parameter could be the Dynamical Time (TD), which is the closest concept we have today to Newton's idea of "absolute" time.

    Geoffrey, to Peter H you wrote:
    "And I don't think I agree with you anyway about just needing one parameter to characterise an LOP."

    Peter Hakel writes in phrases that lead me to believe that his education was in mathematical physics (or something close --correct me if I've guessed wrong!).

    But it's also possible to have a slightly different "spin" on a concept, like whether to define "AP" narrowly or broadly, that is simply a result of the individual path that each of us has taken to get to where we are... Which make me wonder, what parameter could we apply to that path...?
