Seems to me you ought to be able to deal with this on the fly. If you
find multiple hits in the catalog but the image shows only one object,
dump this guy out to a table of observations of unresolved objects. You
could generate a list of potentially unresolved UCAC objects and use
that to see if the current observation might be a problem.
