@henrysky could you check #2429 please? Probably we can use orbital data from italian website https://www.stelledoppie.it/index2.php?section=2

Other problem: I don’t have access to The Washington Double Star Catalog anymore, so, I can’t update data in Stellarium according to changes in our star catalogs (see #425).

Who want and can update WDS data in Stellarium?

[henrysky]

I can deal with the Washington Double Star Catalog by querying SIMBAD as part of the star catalog generation pipeline in the future, but I won't have much free time in the next few weeks so this won't make it in 25.1 and need to wait until 25.2.

Previously edition of part of WDS in Stellarium was added by me through adding WDS synonyms for HIP stars and original data from WDS catalog. I fear getting HIP/GaiaDR3 from SIMBAD as synonyms for WDS identifiers may be painful.

In any way version 25.2 is good for me as target.

What does one have to do? Just download some list from an URL, or process it? Which tools are involved?

My tool for processing - https://github.com/Stellarium/stellarium-data/tree/master/wds

Could anyone check version WDS in VizieR and on official website? Or, better, data in catalogs

[gzotti]

So, I'd just clone stellarium-data on WSL, run the perl script and commit the changed files?

No, perl script just convert the data… So, OK, I’ll try to get the new data through CDS xmatch tool

[gzotti]

Well, I could process such data, but please just add a README to the tools to understand the workflow.

• get data from "URL". (Add additional instructions here when the process requires filling in a form or such...)
• run "converter" "infile" "outfile" "args"
• move resulting 'outfile' to 'where it belongs'.
• add entry in some changelog (?)
• commit whatever has to be committed
