Figure caption: Images from a snapshot RML reconstruction of a simulated 2017 EHT observation of a rotating elliptical Gaussian. The reconstructions, shown in orange, are compared to the model images, shown in blue contours corresponding to 5%, 20%, 40%, 60%, and 80% of the model maximum brightness. The top row of panels are reconstructions of an approximately horizontally oriented elliptical Gaussian, while the bottom row of panels are reconstructions of an approximately vertically oriented Gaussian. The ellipse in the lower left corner of each panel shows the elliptical CLEAN beam. The middle row of panels show the snapshot coverages used to produce the reconstructions shown. The coverage shown in column (a) is produced by the simultaneous observing of ALMA, APEX, SPT, and LMT; in column (b), ALMA, APEX, SPT, and PV; and in column (c), all sites except for PV. Snapshots (a) and (b) have an identical number of baselines in their (u, v)-coverage configuration but different angular isotropy. The (u, v)-coverage in column (b) is relatively capable of resolving the source along the north–south and east–west baselines and orients the reconstruction properly. By comparison, the (u, v)-coverage in column (a) can only constrain flux in the direction of the collimated coverage. As a result, it incorrectly recovers the orientation of the Gaussian. The (u, v)-coverage in column (c) is a maximally (u, v)-filling case for the 2017 array configuration, with baselines relatively evenly distributed both radially and angularly. The result is an accurate recovery of the model behavior.
