I don't actually have Maps, merely copies of the booklet. The XYZ coordinates given there do appear to correspond to the positions of the stars on the Maps, though - that is, they are clearly given wrt Earth's equatorial plane and still claimed to be wrt the galactic plane, placing Antares and Deneb on the wrong sides of Earth and so forth.
The Gamma Equulei thing I don't really know about. However, the Taugan Sector was mentioned in "Gambit II" as lying close to the old Debrune territory, and it might be that Mandel felt the need to associate this with Taugus at the cost of having to move the star. It's something he added to the map after I'd made the semi-arbitrary choices on where the RNZ should be and, thus, where the Debrune ruins should lie.
There are other such additions that IMHO push round pegs into square holes, such as interpreting Iccobar as a star/culture rather than merely a language. But Taugus is probably the only case where a real star suffered from such forcing.
