     Already the IAU nomenclature  committee has anticipated that the
numbering of the faint USNO stars might be different for different editions.
        detection lists generated from scans of POSS-I O and E plates,
        and SRC-J and ESO-R plates.
        Two among first refs containing objects from this catalogue:
        1997IAUC.6731Q...1H, 1997IAUC.6749Q...1Q
