Re:3C 284
4.1.10. 3C 284; z = 0.239; An FR II HEG radio source, hosted by a disturbed
elliptical with a southeast tidal tail toward its most prominent companion 4"
southeast. Several fainter companions are also visible on the NICMOS chip. In
the optical the source has a disky appearance and double nucleus, owing to this
same tidal tail and associated dust lanes.

Re:3C 284
3C 284 (Figs. 36 and 37) has and ELR which is composed of three separate
components in our images. The PA along the overall structure is not aligned with
the source. However, taking an "inner PA" of the central structure gives the
alignment with the radio source, so we consider this ELR aligned with the radio

Re:3C 284
A13. 3C 284 - The XMM-Newton data we use here were analysed by Croston et al.
(2004). Their best-fitting model parameters are in reasonable agreement with
ours, although they fixed the photon index at {GAMMA} = 1.5, rather than 1.7 as
used in this work. Apparent discrepancies in the absorption column affecting the
second power-law component and in the flux densities result from changes in the
XMM calibration files, as for 3C 223.

3C 284, z = 0.2394. - The original HST image (Fig. 21) shows an
object similar to 3C 275. The large-scale radio structure is positioned
in the same direction as the arms of optical emission, perpendicular to
the dust lane.

Re:3C 284
3C 284 (z = 0.24; Fig. 10) -This object lies in a moderately rich
cluster. The continuum image is unremarkable. The [O III] image shows a
small region of extended high surface brightness emission centered on the
nucleus, similar to the circumnuclear emission regions described by Baum
et al. (1988). The [O III] image, however, also shows three regions of
detached emission that lie ~40" from the nucleus. These detached emission
regions lie within 15^deg^ of the radio source axis. The source is a
large 176" double in position angle 101^deg^ (Riley & Pooley 1975; Leahy
& Williams 1984).
