Don't know - Beta 2.00 is too buggy to do very much in yet. I've managed to stay connected long enough (in solo mode) to buy a docking computer and test the improvement they've made to that, but the galaxy map is essentially unusable.
ETA: if anyone does manage to go exploring, I'd like data taken *from* the "coordinate extrema" systems listed previously, or at least the most outlying systems you can comfortably reach, to each of the *other* such systems, and to the following other stars:
Etamin (aka Gamma Draconis)
Enif (aka Epsilon Pegasi)
Alpha Cygni (aka Deneb)
Achenar (aka Achernar, Alpha Eridani)
Polaris (aka Alpha Ursa Majoris)
Mirphak (aka Mirfak, Alpha Persei)
Alphard (aka Alpha Hydrae)
Rigel (aka Beta Orionis)
Sol (aka ... do I have to spell this out?)
Sagittarius A* (aka ... not actually a star.)
Sol should, of course, resolve to (0,0,0), while Sagittarius A* should also lie on one of the coordinate system axes (and is an extremely long way away). They'll therefore make good reference points to determine how accurate the measurement system really is.
The other eight stars listed were selected from the navigation stars by dividing it into octants and picking the most distant star (for which I had coordinates) in each octant. Those can be our long-term reference points, but we need measurements to them from the known, populated systems first, so that we can calibrate their true positions in-game.
