Notes. The total integration time and data size includes all of the seven target fields and the observed calibration sources over both epochs (April 11 and 26). We note that the given integration time and data size describes that of the raw dataset, i.e. before any loss of data due to RFI, noisy data, or “off-source” visibilities.
