Hi Andrew:

I have a feeling we've communicated previously - on this subject? Not sure.

If you're interested, someone else has sort of beaten us to it. Try this
ore-1409. I don't know if the NBOS spam filter will remove the link so. In
case, I'll send it to you off list.

I was aware that GDW had taken some liberties with reality in producing the
Near Star Map for T2300 but, about 5 years ago, I downloaded a free
astronomical prog. called "Cartes du Ciel" and the publishers had a link to
allow the download of the Gliese 2 Catalogue. I managed to get this working
and could convert Gliese numbers to GD or HIP numbers with no problem. I
made some decent progress, then had to move house. In the move, my PC
suffered damage and I lost the work so I thought I'd start again. Sadly, the
Cartes du Ciel software has been upgraded (i.e. made more complex), the
Gliese 2 catalogue no longer seems to be available and, to put it bluntly,
I'm stymied!

I've downloaded one or two data lists that purport to contain the Gliese
data but I can find no sign of anything that looks like the original Gliese
numbers in any of them. I shall persevere and try to keep you posted - and
anyone else on the list who's interested.

2300 uses a slightly modified version of the gliese number. It also used the
gleise 2 catalogue (gliese 3 came out after the game).

There were a couple of errors in the Near
Star List. Furthermore, GDW didn't use any particular coordinate system for
the data. They spun it round in Macspin until none of the stars overlapped.

I looked into using an established catalogue (gliese 2 being the obvious
one) to use in astrosynthesis for 2300ad, but the problems were great enough
that I decided it was easier to manually type the near star list into a
spreadsheet manually.

I'm about halfway through that, I think.

I've just resurrected an earlier project to produce an AS3 map of the real
universe to 50 light years out from Sol for Traveller 2300AD (T2300). I am
using the Kepner_50lyr_stars CSV files provided very kindly by a member of
these lists as the sector file and endeavouring to identify the star systems
from the Near Star List provided with the T2300 game.

I have two problems for which I am seeking help:

1. The Game uses the old Gliese Star Catalogue to identify the systems
but the Kepner file uses Hipparcos, Henry Draper and other catalogues. I
can't find a means of marrying the various catalogue references.

2. When I try to use the Search facility in AS3 to locate systems by
the catalogue number, it returns an error message: 'Unknown search term near
" hd" ' (for the Henry Draper catalogue numbers).

Can anyone please offer some suggestions as to how I can resolve these
issues? If I can get the project finished, I'll put it up for other members
to download (which I had promised to do when I first embarked on the project
4 or 5 years ago. I think Doug Jesse and Roland Volz had expressed an
interest at that time.
