<P> In astronomy , declination ( abbreviated dec ; symbol δ ) is one of the two angles that locate a point on the celestial sphere in the equatorial coordinate system , the other being hour angle . Declination 's angle is measured north or south of the celestial equator , along the hour circle passing through the point in question . </P>
