Corwin's Notes
=====
NGC 998 is often misidentified as CGCG 414-028 = UGC 2102,N2 (the second
object in the UGC Note for UGC 2102) in modern catalogues because the CGCG put
the NGC number on the wrong galaxy. Steve Gottlieb points out that the
correct object -- clearly identified by Marth's relative position from NGC 997
-- is just 1.9 arcmin north-northeast of NGC 997, and is UGC 2102,N1.
MCG is also a bit confused: NGC 997 is MCG +01-07-015 with declination
"+7 04.", while NGC 998 is MCG +01-07-016 with declination "+7 06". The other
information in MCG for these two objects is correct.
