    Dear Bruce,
    Just for the case that you missed this discussion,
    recently frank Reed produced a nice simple formula which
    shows the effect of an error in altitude on the
    cleared distance.
    See, for example, my message Tue Nov 02 2004 - 12:43:15 EST

    "Lunars: altitude accuracy" and
    "90 Degree Miracle".
    Alex.
