Compared to all other catalogs available that are any manageable size, the UCAC-3 catalog
is by far better than the alternatives. There is NO catalog out there that is free of
flaws; I have been using the UCAC-3 since prior to its public release and have found it to
result in far more accuracy in terms of astrometric and photometric precision than other
alternatives.

Nothing is perfect....nothing.
