Realistic 2300AD Near Star map

How do you resolve conflicts in position between the different catalogues? Some of the names differ. I tried doing automating an intersect between Gliese 2 and 3 many, many moons ago and finally gave it up for dead.

EDIT: Oh yeah! Cool map!

Gliese is just all-around wrong - it's long since been superseded by Hipparcos (which has had two different refinements since then!). But if I had to use Gliese, I would just drop Gliese 2 and use Gliese 3 instead (thereby avoiding conflict between them!).

Trigonometric parallaxes win over anything else - those are way more accurate than other distance determination methods. RECONS, DENSE and CTOIPI are all trigonometric, and out of those I hold RECONS as being completely accurate (it's not really, but it's the most accurate of the lot), then DENSE, then CTIOPI. Beyond that HipX is king. LDWARF is "accurate enough" - I'd guess that many of the distances aren't too accurate since most are photometrically determined (not trigonometrically).

There aren't too many conflicts between those catalogues because there's not a huge amount of overlap. But I would never use HipX along with Yale and/or Gliese - they're so different that they may as well describe different universes . Hipparcos would always reign supreme out of those three, and Yale and Gliese should never be mixed because you will get a lot of overlap and duplicates.

(er, did that answer your question at all?)
