I will suggest adding or subtracting 1° to the assumed latitude for the few cases where the sums of latitude and declination are less than 1° when performing a longhand haversine sight reduction. For cases where the meridian angle (t) is less than 1° I will suggest doing an ex-meridian rather than a 4 place hav-doniol reduction.
