Re:NGC 4700
NGC 4700 has been listed as a H II region galaxy in the list of
Rodriguez Espinosa et al. (1987), while Hewitt & Burbidge (1991) list
it as a Seyfert 2 galaxy. It has been included in the HST imaging
survey of nearby AGN (Malkan et al. 1998). NGC 4700 has a relatively
large ratio of S_60_/S_100_ of ~0.51, making it a promising candidate
with a potential DIG halo according to the diagnostic DIG diagram.
Indeed, a relatively bright, and extended gaseous halo with a maximum
extent of 2.0 kpc above/below the galactic plane is discovered. One of
the filaments can even be traced farther out to ~3 kpc. The morphology
of DIG in NGC 4700 is asymmetrical, with the eastern and middle part
being most prominent. Five distinct bright H II region complexes, which
are composed of several individual smaller regions across the disk, can
be discerned. Some prominent filaments above active regions protrude
from the disk into the halo. A small number of bright H II regions is
seen in this part of the disk, and the maximum extent of the eDIG is
visible above those regions. The western part of the galaxy is lacking
in bright H II regions, hence the suppressed extend of the halo in this
western part. NGC 4700 also bears an extended radio halo (radio thick
disk), with the maximum extent correspondingly on the same position
above the disk (Dahlem et al. 2001), although slightly more extended in
the radio continuum image as in our H{alpha} image (see Figs. 8 and 9).

NGC 4700 is difficult to classify because the
spiral pattern cannot be inferred from curvature
in dust lanes, which are usually used for that
purpose. The galaxy here is viewed almost directly
edge on, so that no prominent dust lanes are
seen.
The redshift is v_o = 1193 km/s.

The surface brightness of NGC 4700 is so
high as to mask most of the resolution into
numerous HII regions seen on the original plate.
The galaxy is also illustrated in the Sc section on
panel 291.
The redshift is v_o = 1193 km/s.
