Fig. 2.


Total intensity image of 3C 345 at 1.6 GHz with the ground array data (orange scale) and all data including the space baselines (blue contours). The different beam sizes are displayed in the bottom right corner. We reach a resolution of 1.25 × 0.32 mas with RadioAstron. Contour levels are in percents of peak emission of 0.39 Jy beam−1: 2.83, 4, 5.65, 8, 11.31, 16, 22.63, 32, 45.25, 64, 90.51. For the ground array image, the resolution is 3.0 × 2.1 mas, and the colour-scale shows the total intensity in log-scale between 0.5 and 100% of the peak of 1.68 Jy.
