However, in this particular case the Mongoose material aligns perfectly with the CT material. The Mongoose map from the OP shows the same Upper case Greeek Eta at Junidy as the 1981 map did. If TravellerMap says otherwise for the same era, it's far more likely to be an error of TravellerMap.
And it would certainly NOT be astounding if someone misread a Greek letter and put in the wrong name.
Edit: including me. That OP map has an uppercase Gamma at Judice. Are Mongoose using a Gamma to mark all Research stations on that map instead of the actual station name? I know GDW used the Gamma as the example of a Research station's presence on the key, but the seven SM stations were shown with their actual symbol.
Map aside, the UWP listings should say if a station is present or not, in the notes.
