Source Alignment

NVSS 2146+82 is not aligned along a single axis. The two warm regions (E and D) and the core (C) are not collinear. The jet in the south appears to have several bends; one near the end of J1 (see Figure 4) where it bends toward J2, a change in position angle from -150 to -170. Beyond J3, the ridge line of the lobe is fairly well defined and is again at position angle -150, consistent with a second bend (apparently tex2html_wrap_inline1366 20) in the neighborhood of J3. The jet is not so prominent in the north but feature K, which may be the brightest part of a counterjet, is elongated along position angle of -169.

The general ''C'' shape of the source suggests that the overall misalignment is due to environmental effects that have bent the jets, rather than to a changing initial jet direction which is likely to produce overall ''S'' symmetry.

We consider it beyond doubt that C, D and E comprise a single large FRII radio source with weak radio jets, whose parent object is the galaxy identified with C.
