Bug Description

In some cases the search for HR objects does not work exactly. For example, when searching for HR 2175, the star HIP 29388 A is selected. But HR 2175 would only be the component B of this double star, the other component A would have its own number HR 2176.

Stellarium gives the same HR and HD cross-id to both components. This is confusing for cases where components are displayed and can be selected separately.

Below is a list of some brighter double stars with the respective HR, HD and SAO cross-id.
A few of them also have different Bayer designations (e.g. α1, α2).
I have extracted these data mainly from "Bright Star Catalogue, 5th Revised Ed. (Hoffleit+, 1991)".

It would be nice to have the cross-ids also in Stellarium, to avoid confusion when searching and selecting double star components.

Great update, thank you!

But I noticed that the cross ids of HIP 1 got lost.
This was probably not intended!?
