This is not as trivial a question as one might think, since it is not enough to know the location with respect to the Earth and/or the Sun in some arbitrary coordinate system. One may have to consider things like differences between the solar equatorial plane and the Earth's orbital plane, the changing direction of Earth's spin axis during the year, and the magnetic dipole orientation. ...

... Coordinate system . It is necessary to specify the coordinate system for the drilling of plug-plates so that the drilling file (currently named plPlugMap), plate drilling, cartridge, rotator wrap and the rotator itself are compatible. ... The TCC rotator angle (object system) is defined to be 0 degrees for this orientation. ... Thus, the rotator angle gives the conventional astronomical position angle on the sky of the y axis (although Russell won't acknowledge this necessarily). ...
