| Declination, not magnetic declination, is the bearing of a
| celestial body
| from the observer. When coupled with elevation, a line of position can be
| obtained, Cross two or better three, lines of position and you have a
| geographic location or "fix". Talk to a navigator and you will understand.

Not to be confused with right ascension...which has nothing to do with
Christianity.
