3C 456, HEG, 1″ = 3.51 kpc. The black circle in the first panel has a diameter of 3 times the seeing of the observations; the dashed line in the second panel marks the radio position angle. The outflow maps of this source are very similar to the ones obtained for 3C 327. In this case the emission lines are just more extended: the outflow is enclosed into an area of radius ∼7.02 kpc. In the west region the redshifted component is detected (up to ∼1100 km s⁻¹), in the east the blueshifted one (up to ∼ − 1900 km s⁻¹). The image is clearly resolved, the energy peaks on the nucleus and decreases towards the border.
