The names, star types and locations would be correct (as best as is known, anyway). Mass, luminosity and radius data would be generic placeholders.

Nifty.

Are the systems time-corrected, or just e2000 positions?

In other words, if a star is 100 ly away, are its coordinates what they are today or 100 years ago?

Nope. The locations are based on the J2000 coordinates of the stars as we see them today. It doesn't account for proper motion at all.

I've now added 164 stars from the CTIOPI dataset from the RECONS website, and also updated the DENSE data. See http://evildrganymede.net/2012/02/27/st ... opi-added/ for details.

If you've downloaded the datasets previously, you'll need to download the updated versions!

I've now replaced the New Reduction Hipparcos data with the brand new Extended Hipparcos dataset, so if you downloaded that previously then please head back and download the new data! Also, my stellar mapping site now proudly bears the Atomic Rockets Seal of Approval! :)

See http://evildrganymede.net/2012/03/12/stellar-mapping-extended-hipparcos-dataset-added/ for details!

I’ve added a new Brown Dwarf dataset to the Stellar Mapping page! This should hopefully be the last major update to the stellar datasets for a while – the next project on the list is to figure out what the reworked Arms for 2300AD might look like based on the realistic data.

I've also made some major updates to the other datasets on the Stellar Mapping page, so if you're using them then you'll want to download the new versions!

See http://evildrganymede.net/2012/03/25/stellar-mapping-brown-dwarf/ for more details!
