Notes. The beam of each observation was centered on the reported pulsar coordinates. The bottom rows list the earlier periodicity and single-pulse search limits. The upper limits from Frail et al. (2016) described in the main text are period-averaged flux densities and are not listed here. The last row lists the limits from the current work for S/N = 5, with errors of 50% (Bilous et al. 2016).
