Corwin's Notes
=====
NGC 7697 = IC 5333 = ESO 110-G012. Steve Gottlieb points out that the three-
minute RA error in the NGC could well be a simple typo, while the ten-arcmin
Dec error is apparently a digit error introduced in the GC precession. JH's
original position in the CGH Observations (23 25 03.7, 156 20 34 for 1830)
precesses to within 30 arcseconds of the modern position. Had the CGH
position appeared in the NGC, Stewart would not have listed this as a new
object.
That modern position, by the way, is not well-constrained. The galaxy is a
stubby, patchy spindle with no obvious nucleus. The declination is pretty
well-determined as the galaxy is extended nearly along the equator. The RA,
however, is a problem. I've given several in the table; the one I've chosen
-- a mean from the 2MASS PSC -- is appropriate for the approximate center of
the image, but does not necessarily represent the nucleus.
The printed version of RC3 is wrong. The correct identification there is
PGC 71800 = NGC 7697 = IC 5333, and the type is .S..3P/, with S(T) = S, T =
2.5 +- 0.7 (I now think the type is actually later than Sb, but we need a deep
image with a large telescope to tell for sure). Also note that PGC 71812 is
not NGC 7697. Therefore, the type for PGC 71812 is ".SBT6..", and T =
6.3 +- 0.6.

NGC 7697
Southern object (not observed). Incorrect position/identification in the RNGC.
