$\begin{figure} \par\resizebox{13.8cm}{!}{\includegraphics[clip]{3347fig1.eps}} \end{figure}$ Figure 1: Images and spectrum for 0222+36. a) VLA at 8.4 GHz, b) VLA at 22.5 GHz, c) VLBA at 1.6 GHz, d) spectrum. Contours are traced at (1, 2, 4, ...) times the $3\sigma$ noise level; observational parameters (beam size, noise level, and peak brightness) are given in Table 3. The cross in the VLA images indicates the position of the VLBA core. The integrated spectrum is derived from data in the present work and from the literature (see Sect. 3).

Contours are traced at (1, 2, 4, 8, ...) times the $3\sigma$ noise level. The lowest contour is $69~ \mu$ Jy/beam, the peak is 209 mJy/beam. The beam is circular with a HPBW of 1.2 $^{\prime \prime }$ .
