RCW catalogue

[theskyhound]

Greg does ST4V contain the RCW catalogue of HII regions?

Hello,

Yes. It may not have every single cross reference, and sometimes a nebula might be missing entirely. This is because the data comes from another, more reliable, catalog, and the RCW cross references were added. I note that RCW 42 isn't there. Not sure why, but it likely has to do with questionable cross references. If you run into more of these that should be added, let me know.
