    It is not really necessary when calculating zenith distance directly to convert this to Hc.  Just sum the calculated ZD and the Ho.

    excess over 90, intercept is towards

    deficit from 90, intercept is away

    trivial, I know, but saves a step and is easy to remember.

    Nice job Hanno!
