Naturally weighted wide view VLBI image of J1433+4842 at 1.63 GHz. It includes the first Gaia position (GAIA1) the second Gaia position (GAIA2) and the extended emission that lies between the two positions (EXT1). To note that the shape of EXT1 in the picture is not exact the same with the zooming-in images showing in Fig. C.1 due to the bandwidth smearing effect caused by the large distance between the source and the image phase center (I used the GAIA1 position as the big image’s phase center). The lowest contours represent 4σ (σ the post-CLEAN background noise) and contour levels increase by a factor of 2.
