  Basically this is a matching problem, not a seeding problem.
As Dirk mentioned, the proper way to handle this is if more
than one star in the UCAC catalog falls within the matching
range of the imported coordinates, then identify the imported
object with, say, the brightest UCAC object,
but flag it as 'unresolved' or 'blended'.  Take UCAC as the
Bible; it will have every normal object that a TASS camera can
detect.  There will be a few new objects such as novae and
asteroids, but they will be a very small subset.
