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.

   
Clear skies,

Probably the new SN remnant RCW 86 could do with being added. As you say many of them already have NGC/IC or Gum numbers anyway.
