    Re: Quad regression for Lunar Distances?

    Robert,

    Thank you for your detailed paper concerning rate of change of altitude with respect to parallax. I realized the other day that HP has to be expressed in radians when calcultating difference in rate of change. I have but two very minor objections to your paper: You state that radians are "dimensionless". I would argue that radians have dimension = 1. And in your (12), shouldn't it be (360·60/(2·π)) in your conversion multiplier, or (180·60/π)?

    Lars
