Declination

(dec)
(direction coordinate above/below celestial equator)

Declination is a coordinate for a point in the sky consisting of the angle to it measured from the nearest point on the Celestial Equator. It and Right Ascension (RA) together specify a direction, i.e., a point in the Celestial Sphere. Declination and right ascension are analogous to latitude and longitude, respectively.
