EHT images of 3C 279 on each day, generated by three different pipelines, then aligned and averaged. See Paper IV for details on the method. The circular 20 μas restoring beam is shown in the bottom right corner of each panel. The pixel values are in units of Jy beam−1. In each panel, the contour levels are 5%, 12%, 25%, 50%, and 75% of the peak value. The component identification is shown in the April 11 panel and is only for illustration (see Fig. 6).
