Updated stars.dat including Gaia EDR3 data (update 2022-03-03)

[DrJMOS]

It looks like the problem is that the old version of nearstars.stc that comes with Celestia 1.6.x is missing TYC designations for Gliese 667 A and B, which will result in duplicates with the updated star database. This has been fixed in the current version of nearstars.stc, so just replace it.

See here for a guide to keeping Celestia's default content up to date.

Hi SevenSpheres, omg is true, even I've edited nearstars.stc removing all the duplicate stars there and now works fine. Very helpful your answer,



Regards!!

New pre-release. Main fix is in the code used to select Gaia-based or HIP-based distances in the EDR3-based databases. This wasn't fully updated from when it was only operating on the Hipparcos subset of the data, a notable symptom of this is a "bubble" of stars at ~913 light years. This should be fixed in this release.

There are a few other fixes, including an issue where 64-bit integers failed to roundtrip to the Gaia TAP endpoint leading to TYC2 supplement 1 stars having incorrect IDs.

As there are still a few more things I want to update, I'm giving this a prerelease version number.

Can someone give the file stars.dat (from celestia-gaia-stardb-1.1.1), only in text (readable) form?

Here's a Python script to dump the database to CSV

Usage:

Code: Select all

python3 dump_starsdat.py /path/to/stars.dat /path/to/output.csv

If you don't supply an output file, it writes to stdout instead.

Columns:

• id - numeric ID
• catName - the numeric ID translated into a HIP or TYC number
• x,y,z - rectangular coordinates of the star (light years, ecliptic frame)
• absMag - absolute magnitude
• spType - spectral type

Thanks.
