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.
