4.86-GHz VLA-A map of Complex B. Peak intensity is 78.7 mJy beam⁻¹, lowest contour levels at 3σ rms noise level, 0.6 mJy/beam. Further contour levels increase by a factor of two. Beam size is 0.″ 43 ×0.″41 at a position angle of − 39° shown at the lower left part of the image. Cross indicates the pointing position of the EVN experiment EL034A, star indicates the pointing coordinates of the VLBA experiment BL189. Ellipse shows the position of the fitted elliptical Gaussian component to the EVN data. Its size is multiplied by 5 for clarity.
