ALMA maps of the 92.2 GHz emission (colour scale, saturated to emphasise the emission from the SW lobe), after subtracting the dust contribution (see text). The contours are the map of the 22.2 GHz continuum emission obtained in 2023. Contour levels range from 0.34 to 2.72 in steps of 0.34 mJy beam⁻¹. The ellipses in the bottom left are the half-power widths of the synthesised beams. a. Obtained from the ALMA data acquired on June 6, 2019 (see Paper II). b. Same as top panel, but for the data obtained on September 3, 2021.
