Notes. Columns indicate the barycentre spin period of the candidate (Pbary), the significance of the signal as given by PRESTO sifting.py (σ), the acceleration estimated by accelsearch (accel.), the epoch of the observation, and the frequency band (Dataset) that produced the candidate. An asterisk after the frequency band indicates the candidates shown in Fig. 5.
