    Except, perhaps, to make it clear that the sight reduction tables and
    azimuth determination are separate, one doesn't affect the other.
    And that a number of methods for azimuth determination are offered, the
    possible 'error' only affects one method when azimuth is close to east or
    west, which could be a good time to check it against another method.
