Hi again,

I'm doing a bit of research about the positioning of the galaxies (the local group in particular) and I was wondering if there were any lists available where the cartisian coordinates were already calculated as apposed to translating them from the polar coordinate vectors.

I've found these if anyone's interested:

Stars within 75 light-years

Calculating coordinates and distance etc

The Tully database is probably your best bet.

Is it only available with Starry Night Pro v.4?

Tully's collection of 2367 galaxies (Nearby Galaxies Catalogue, VII/145, 1998) is available everywhere, such as:

http://xml.gsfc.nasa.gov/archive/catalogs/7/7145/

Here's another database, GOLDmine, which you might find useful:

I am unable to find the 28,000 galaxy Tully database in downloadable form. Several preprints have used Tully's data, but all give him as a reference via "personal communication." I suspect that this means he is not completely done with the data, and has not officially released it yet. Chances are the Nearby Galaxies Catalogue will be sufficient for your purposes.
