Trying to get the number of objects not found in a crossmatch
So, using the astropy python module I'm trying to crossmatch a list of objects with simbad. Using astroquery I'm getting a certain number of results and errors telling me no astronomical object found and that these are recorded in the 'errors' attribute of the result table. I want to make an HR plot of my list of objects and then overlay the number of objects recovered in my crossmatch but I can't seem to figure out where to get these objects which weren't recovered in my crossmatch.
Another function I could use is XMatch.query(), as I think that might return a combined table, rather than query_region() which simply returns the objects that were found. I can't figure out how to get that function working however.
Any thoughts on how to go about this?
