Continuum emission at 2.1 GHz (left panel) and 5.5 GHz (right panel), in colour scale, without primary beam correction. In both panels, the Half Power Beam Width (HPBW) at 5.5 GHz (larger) and 9.0 GHz (smaller) are marked with dashed lines, while the HPBW at 2.1 GHz is outside the images. The emission at 9.0 GHz is shown in white contours, with levels of 6 (3σ), 23.6 and 41.3 mJy beam⁻¹. The small and closed contour level at the centre of the images represents the location of HD 93129A. The almost circular source towards the bottom left corner is η Car.
