... Maps of six sources (0420+022, 0420-014, 1308+326, 1345+125, 1803+784, and DA 193) obtained with milliarcsecond resolution are presented and discussed, together with their broadband (1­22 GHz) spectra obtained on the RATAN­600 radio telescope at epochs close to those of the VLBI observations. ... The image (Fig. 5) shows that the source structure at 18 cm is compact, consisting of a VLBI core and two jet components, with the outer component lying 5 mas (30 pc) to the northwest of the core ( = 54 ). ...
