I really really really want a graph with error bars. I want the positions of the stars with error bars. Last year I looked for a while, but failed. :(

The raw data is important for specialist, an I'm not planing to do an astrophysics course.

The artistic impression is perhaps nice for laymen (but I think they deserve better).

I want my error bars!

So, looking at the research article, I found this graph

https://www.aanda.org/articles/aa/full_html/2026/06/aa57431-...

Note that is rotated like 180° from the ilustration in the press article.

I love it. I love error bars. I love that the error bars are huge and that somewhat explains why it's difficult to get the right distance and the best current guess must be updated.
