    To compute lunar distances (or great-circle distances) that exceed
    90 degrees using tables, can't you simply compute the distance to
    the diametrically-opposite point, and then subtract from 180?
    The great circle from the moon's position to the sun's position,
    when extended, passes through the point diametrically opposite the
    moon...
