VLBA and EVN maps of RBS 797 at different frequencies. Top panels: VLBA images at 1.6 GHz, 5 GHz, and 8.4 GHz. The beam sizes are 6.3 × 4.6 mas at 1.6 GHz, 2.2 × 1.4 mas at 5 GHz, and 1.3 × 0.9 mas at 8.4 GHz. Bottom panels: EVN images at 1.6 GHz and 5 GHz. The beam sizes are 9.1 × 6.7 mas at 1.6 GHz, and 2.6 × 1.6 mas at 5 GHz. In each panel, the beam is shown in the bottom left corner, and contours start at 5σ_rms and increase by a factor of 2; the first negative contour at −3σ_rms is drawn in dashed red (see Table 2 for the resolution and noise levels of the images). The 1.6 GHz VLBA and EVN images have a matched field of view. The white dashed square shows the extent of the images at 5 GHz (EVN and VLBA) and at 8.4 GHz (VLBA). Structures discussed in this work are labeled.
