Contour maps of Proxima at 1.62 GHz during maximum and minimum emission. Top panel: emission on April 28, 2017, when the flux density was at its maximum. Contour levels are drawn at −6, −3, 3, 6, 12, 24, and 48 × 78 μJy beam−1, the rms of the map. Bottom panel: map obtained by combining the uv data for the observing epochs when the emission was not detected in each of the individual images (April 16, 20, 22, 23, and 26, 2017). Contour levels are drawn at −2, 2, and 4 × 38 μJy beam−1, the rms of the map. In both maps the solid and dotted contours represent positive and negative levels, respectively.
