Two examples to illustrate the challenges that arise when matching optical images with a resolution of  ~2″ to radio images with a resolution of 45″. The contours show the radio emission from NVSS; 2MRS galaxies are labeled with green pentagons. The entries of the NVSS catalog are shown by purple squares, we see that both jets are decomposed into multiple elliptical Gaussians (6 for NGC 383 and 11 for UGC 7115). The radio entries matched to this galaxy by the angular distance requirement (Eq. (1)) are labeled with crosses. For UGC 07115, the remaining four jet components are included after applying a friends-of-friends algorithm (Sect. 2.2.1).
