Naturally weighted 1.7 GHz EVN+e-MERLIN high-resolution VLBI map of AT2019aalc. The peak brightness is 17.3 mJy beam⁻¹. The gray ellipse in the lower-left corner represents the Gaussian restoring beam. Its parameters are 4.82 mas × 3.7 mas (FWHM) at a major axis position angle of PA $=60\stackrel{°}{.}8$. The lowest contour level is drawn at ±3σ image noise level corresponding to 0.08 mJy beam⁻¹. Further positive contour levels increase by a factor of 2. The red dashed contours represent the negative contours. The yellow ellipse is the fit Gaussian modelfit component used to describe the brightness distribution of the radio source.
