Polar Distance
</dt>
Angular distance from a celestial
pole; the arc of an hour circle
between a celestial pole, usually the elevated pole, and a point on the celestial
sphere, measured from the celestial pole through 180 degrees.
</dd>
If the declination, d, and the celestial pole are of the same name, the
polar distance is 90 degrees - d, but if of contrary name, it is 90 degrees +
d. See codeclination.
