Near-Sol star datasets (within 300ly) now available for AS3!

Postby EDG » Mon Jan 30, 2012 5:22 pm

My new Stellar Mapping page is finally online! You can check it out at: http://evildrganymede.net/rpgs/stellar-mapping/

This is a complete rewrite of my previous "Realistic Astrography" page, and now includes Equatorial to Galactic co-ordinate conversion files, the complete RECONS (2012) for stars within 23 lightyears of Sol, as well as all the data from the DENSE, Hipparcos, Gliese 3, and Yale catalogues for stars out to 300ly from Sol!

I've also included all the data in Astrosynthesis 3.0 format, which can be imported as CSV and then used in the program! You'll be wanting to look at this if you want the most accurate and complete near star data that is currently available!

Minor update - the 2D RECONS map at the bottom of the page now has the correct orientation, thanks to the 3.01c update that was just released!

New article! http://evildrganymede.net/2012/02/04/ma ... -database/

In this blog article, I describe how to use the VizieR database to make your own stellar database with Galactic XYZ co-ordinates (and how to import it into Astrosynthesis too)! The example provided is a corridor between Sol and the Pleiades (2300AD RPG fans will recognise this as the Bayern corridor!), going out to 500ly from Sol and including the Pleiades themselves. I've also updated the Stellar Mapping page and included the Pleiades Corridor there as a download!

ARGH! I forgot a star! Gliese 667 slipped through the cracks (which is slightly embarrassing since it's a bit famous for having planets around it...). It was within 22.8 ly from Sol, but not on the RECONS list and because it was so close it wasn't on the HIP list either. I've now added it to the RECONS CSV files! (I only found it because I was checking the stars on the American Arm for 2300AD!).

You'll want to re-download the RECONS files so you can include that star in the data too!

Xi Ursae Majoris was left out too (for a different reasons), but is now back in the HIP database. Again, you'll have to download the Hipparcos dataset again from the Stellar Mapping page to include it.

I've added an "Updates" section to the Stellar Mapping page so keep people informed if I find any more missing stars (and so I don't keep spamming boards with these updates!), so check back on the page every now and then for any more updates!

I have loaded these files into Astro Synth 2 and they work just fine as far as I can tell. :)

BTW...have you considering taking the HabCat file and turning them into galactic and AS3 coordinates?

;)

Apparently HabCat consists of stars taken from the Hipparcos catalogue, so I think most of them would are already be included in the Hipparcos data on my site :)

I suppose I could make a separate HabCat file at some point though...

Yes, it is taken from that dataset, and yes many of them are in your files.

You stop at around 300 lightyears with around 20,000 stars.

The HabCat file has around 17,000 stars, with 75% of them within 450 lightyears of Earth.

Therefore, a large number of them would be outside what your numbers do.

I just think it would be really cool to have them in the program as they would probably be useful for a LOT of people who want to do use systems with a high probability of having habitable worlds. ;)

It looks like the next catalogue to be uploaded will be the CTIOPI trigonometric parallax catalogue (another dataset from the RECONS crew, at http://www.recons.org/publishedpi ) - hopefully that will happen this weekend. I'll take a look at the HabCat one at some point and see what it contains and how easy it's be to import.

CTIOPI would add 77 stars to the list within 50 ly of Sol (and beyond the 22.8 ly RECONS sphere), and 184 stars to the total dataset.

Cool.

And each of these you are making certain that the star types are right, or just the locations?
