Closure phases (left) and log closure amplitudes (right) for selected triangles and quadrangles plotted as a function of observing time. The stations forming each triangle or quadrangle are indicated in the top-left corner of each panel. Closure quantities derived from the imaging and modeling results are shown in different colors, demonstrating a good fit to the data. The shaded areas indicate the uncertainty range or variability in the closure quantities. Filled circles represent results from April 5, while open squares correspond to April 10. The antenna codes correspond to AA (ALMA), AZ (Submillimeter Telescope), JC (James Clerk Maxwell Telescope), LM (Large Millimeter Telescope Alfonso Serrano), PV (IRAM 30 m Telescope), JC (James Clerk Maxwell Telescope), SM (Submillimeter Array).
