Extended Data Fig. 2 | Visibility phases measured for two bright
point-sources and FRB 190523. Only data on baselines including fully
functioning antennas are shown. The visibility data were phase-rotated
to the known (or best-fit for FRB 190523) source positions, and averaged
across the frequency band. Data on the shortest baselines (to the left of
the dashed vertical line) were corrupted by correlated noise, and were
discarded from imaging analysis. All data were calibrated using the same
calibration solution, which was partially based on the J1200 + 7300
data, and were obtained at the same hour angle relative to the meridian
within a 12-h timeframe. The x axis shows the baseline lengths in units of
wavelengths at the middle of the DSA-10 frequency band.
