    It is an argument that the precision of marine sextant measurements
    is such that we need not bother ourselves about the difference
    between UT1 and UTC, but for other users of the NA such as surveyors
    or land based navigators who would use a theodolite, the limiting
    factor becomes the accuracy of the NA tables and their accuracy is
    better than one second.
