Corwin's Notes
=====
NGC 7100 is a star at Bigourdan's position. Unfortunately, his position as
first published -- and as copied into the NGC -- is 14 seconds too large in
RA, and 3 arcmin too small in Dec. This, combined with a 6 arcmin error in
Marth's Dec for NGC 7101, has led several cataloguers to put the number 7100
on the galaxy that is properly called N7101. Marth's RA is correct and leads
us to the right galaxy.
The confusion began with Spitaler (copied into the Notes in both Index
Catalogues), and continues today in UZC and LEDA. Bigourdan got the
identifications correct, and his micrometric offsets -- when re-reduced --
lead to the correct objects. The identifications I've adopted are
Bigourdan's.
