Should [SortMerge.jl](https://github.com/gcalderone/SortMerge.jl/) be in the list?  
It is not as polished as FlexiJoins.jl but its performance are very good (e.g. it can cross-match 2 catalogs each with 10^6 entries in ~2 sec, [example here](https://github.com/gcalderone/SortMerge.jl/?tab=readme-ov-file#match-arrays-of-geographical-coordinates)).

Also, @barrettp, is the JuliaAstro Zoom meeting open to anyone?  
I would really like to participate… 😉
