Naturally weighted 1.7 GHz (top) and 4.9 GHz (bottom) EVN maps of galaxy G3. The grey ellipses in the lower-left corners represent the Gaussian restoring beams. Their parameters are 4.75 mas × 4.61 mas (FWHM) at a major axis position angle of PA at 1.7 GHz, and 2.13 mas × 1.10 mas (FWHM) at a major axis position angle of at 4.9 GHz. The lowest contour levels are drawn at ±3σ image noise levels. They are 0.06 mJy beam⁻¹ at 1.7 GHz and 0.07 mJy beam⁻¹ at 4.9 GHz. Further positive contour levels increase by a factor of 2. The peak brightnesses are 0.6 mJy beam⁻¹ at 1.7 GHz and 1.0 mJy beam⁻¹ at 4.9 GHz.
