Snapshot of the calibrated data for Sgr A^* at 7:23 UTC on April 25 from the SEFD-based data reduction. The colored circles represent the combined visibilities of the minispiral and Sgr A^*. The solid colored lines are the mean flux density in each spectral window. The gray-shaded area represents the range of visibilities we consider for the minispiral (0-50 m). The red-shaded area represents the flagging cutoff for the extended structure used by SMA (0-30 kλ).
