Natural weighted total intensity images for the five 86 GHz GMVA observing epochs from 2015 (left) to 2017 (right). The MJD epoch is indicated in the top-left corner in each image. The restoring beam size, shown in the bottom-right corner in each image, is 0.29 mas × 0.06 mas (at −12.8°), 0.25 mas × 0.04 mas (at −10.1°), 0.23 mas × 0.06 mas (at −11.5°), 0.21 mas × 0.05 mas (at −11.2°), and 0.24 mas × 0.04 mas (at −6.5°) from left to right, respectively. The overlaid lowest total intensity contour is at 1% of the map peak (0.54, 1.11, 2.30, 2.53, and 0.68 Jy beam⁻¹ from left to right, respectively), with the contours that follow a factor of two higher. The image rms noise from left to right is 0.54, 1.03, 2.71, 4.15, and 3.47 mJy beam⁻¹, respectively. The color scale represents the total intensity. The overlaid red circles represent the model-fit components.
