Notes. Column 1: observation number. Column 2: LOFAR cycle. Column 3: LOFAR observation ID. Column 4: date and start time of the observation (UTC). Column 5: duration of the observation. Column 6: target elevation range. Column 7: number of bad stations present during the observation found by examining the station inspection plots. Column 8: amount of RFI masked by the BOREALIS pipeline. (1) This observation was not use in the analysis due to near-continuous RFI at all frequencies for the entire observing period. In addition, during this observation, there was also an antenna cable delay compensation issue (communication from ASTRON Radio Observatory staff).
