NGC 943 mis plotted and PGC numbers incorrect for NGC 942 and NGC 943

NGC 943 is incorrectly identified as being at the location of PGC 9459. It should instead be plotted in a tight pairing with NGC 942. NGC 942 is incorrectly identified with PGC 9458. NGC 942 is plotted in the correct location, but should be equated with the equivalent label PGC 9457.
