@StefanJordanARI Hallo Stefan, eine Astrozeitschrift will von mir die 'wahren Distanzen' der Kugelhaufen M 13, M 92 und NGC 6229 wissen, deren EDR3-Parallaxen ich in https://t.co/0ck9GTeqhj fand - wenn ich da einfach die Reziprokwerte nehme, was für Fehle…
@Jos_de_Bruijne Hi Jos, an astronomy magazine is asking me for the "true" distances to the globular clusters M 13, M 92 and NGC 6229, and in https://t.co/0ck9GTeqhj I find their EDR3 parallaxes: if I "simply" calculated distances from those, what formal…
RT @Jos_de_Bruijne: Btw, another impressive conclusion is that "#GaiaEDR3 parallaxes (after applying the zero-point correction suggested by…
