Notes. Positive and negative PA values are measured N to E and N to W, respectively. (⊗)J0907+46. PA3rad refers to the axis that joins the radio core and the centroid of the distant, strongly bent jet or lobe (Fig. 4). Hα emission has not been detected at similar distances or elongated at similar PA. Thus, ΔPA3 cannot be measured. PA3rad is quoted for completeness.
