Locations of observing stations and ground tracks for the occultation of the primary star. Gray squares are locations of observers with bad, unconstraining, or no data; red diamonds for positive detection; and blue circles for no detections (see Table 3 and Figure 3 for more information about the sites and their data). The gray hatched region shows the RECON prediction using a diameter of 220 km (5% albedo) with the 1σ uncertainty in black dashed line. The red shaded regions are the shadow of the primary component (bottom) and secondary component (top) of the object occulting the primary star using the nominal parameter values of the favored model (Table 7).
