position_angle# astropy.coordinates.position_angle(lon1, lat1, lon2, lat2)[source]# Position Angle (East of North) between two points on a sphere. Parameters: lon1, lat1, lon2, lat2Angle, Quantity or floatLongitude and latitude of the two points. Quantities should be in angular units; floats in radians. Returns: paAngleThe (positive) position angle of the vector pointing from position 1 to position 2. If any of the angles are arrays, this will contain an array following the appropriate numpy broadcasting rules.
