Notes. Columns are the LBCS observation number (equivalent to that maintained in the LOFAR Long-Term Archive); the right ascension of pointing position of the observation of the source; the declination of the pointing position; the observing date and time; the description of the source fringe detections to each of the LOFAR international stations (see text); and a quality flag for the observation in terms of the proportion of sources in a single observation that are detected. In general, below 20% indicates a possibly bad observation and below 10% indicates an observation that is likely to be bad.
