3C 54. The HST observations reveal a compact nucleus in this galaxy
with an extension to the southwest in P.A. 220^deg^ (McCarthy et al.
1997). There is a compact object near the end of the 2" extension
from the nucleus. It is unclear if the extension is a bridge, tidal
tail, or jet. There is another companion object a few arcseconds to
the southeast. In Figure 26 we see that this source shows a LW1-type
lobe morphology. No radio core is observed. The northern hot spot
shows two components in the 5 GHz image. 3C 54 shows a jetlike
structure extending toward the southern hot spot in the 5 GHz image.

extension to the southwest in P.A. 220^deg^. There is a compact object near the
end of the 2" extension from the nucleus. It is unclear if the extension is a

3C 54 (z = 0.83; Fig. 42).-This object is quite compact both in the
continuum and in [O II]. The continuum image is moderately elongated
north-south as is the [O II] image, although the latter appears to be
rounder. The radio source is a large 54" double, oriented 25^deg^ east of
3C54 (Fig. A1b). In K the object has a clear extension to the south-
south-west, resulting in a position angle determination of 27^deg^. The
radio source is a large (53 arcsec) double in position angle 26^deg^
(Macdonald, Kenderdine & Neville 1968) and so, although the K-band image
is fairly compact, this is an excellent example of an aligned galaxy. The
optical position angle given by McCarthy et al. (1987b) is 20^deg^, and
comparison with the optical continuum and [O II] images by McCarthy
(1989) show the K-band structure to be very similar to that in the
optical continuum (the [O II] structure is less similar, although it is
elongated along a similar position angle). Eisenhardt & Chokshi (1990)
also presented a K-band image of this object showing a component to the
