LBA snapshot images of AB Dor A at 8.4 GHz (as defined in the text) in red contours, while the dirty beam of the corresponding snapshot is shown in grayscale. Different epochs are shown in different rows. Within the same epoch, the contour levels are the same and the beam size represents the average of the beam sizes of all the snapshots of such epoch, with 0° inclination for easier visualization. The full width at half maximum (FWHM) beam size, its orientation and lowest contour level (the remaining levels are spaced by factors of 2) for each epoch are as follows: (2007): 1.7 × 2.7 mas at 0°, 10% of 3.01 mJy beam⁻¹; (2010): 2.5 × 3.6 mas at 0°, 15.5% of 2.46 mJy beam⁻¹; (2013): 1.5 × 2.2 mas at 0°, 8% of 3.84 mJy beam⁻¹.
