azimuth, from the Arabic
as sumat, way or direction, a term used in
navigation for the
bearing of a celestial body. Geometrically it is the measure of the arc of the
horizon that lies between the elevated pole (north in the northern hemisphere, south in the southern) and the point where the
great circle passing through the celestial body cuts the horizon. Separate azimuth tables were common in the days before modern altitude-azimuth tables came into use for sight reduction for
celestial navigation. Azimuth tables were also commonly used for checking
magnetic compass error at sea.
