This method performs one of the fundamental astronomical calculations: converting a position in the sky expressed in horizon coordinates to the corresponding position in equatorial coordinates.
To do this conversion, we must know the time and place.
For an AltAZ instance , this method
returns a position in equatorial coordinates as a AARADec instance.
AA.raDec(lst, latLon)
lst
The local sidereal time at the observer's
location, as a SiderealTime
instance.
latLon
The observer's terrestrial position, as a LatLon instance.
