Total Intensity Features

The following features of 3C353 are evident from Figure 1:

  1. The jet and counterjet, which comprise about 1% of the total emission from the source, are both well-collimated.

  2. Both jets brighten significantly beyond ~10/h kpc from the nucleus.

  3. Both jets contain knots   of enhanced brightness within more diffuse, roughly parallel-sided (i.e., slowly-expanding), emission.

  4. Both lobes are highly filamentary. Filamentation   in the West lobe confuses the outer path of the counterjet, so it is hard to identify which, if any, features in the outer lobe might continue the counterjet.

  5. The integrated flux density of the jet is between two and three times   that of the unambiguous segment of the counterjet.

  6. The jet, which is relatively straight   along p.a. 73.8° for most of its length, can be traced all the way from its first bright knot to a well-defined, oblique hot spot   that has a prominent arc of emission on its north rim.

  7. In contrast, the counterjet first appears at p.a. ~78.5°, then deflects to p.a. ~85° before reaching a complex ring of emission containing much substructure but no well-defined ``hot spot".

  8. Although the jet is straight, its centerline does not point to the nuclear source; its north edge aligns   better with the nucleus.
