Single-pulse search carried out with PRESTO on 19 November 2022 for the DM range. Time = 0 corresponds to the start of the observation. Each circle represents a pulse detected with a S/N ≥ 8; its size is proportional to its S/N. The dashed horizontal line marks the DM of the magnetar (178 pc cm⁻³). The pulses align in elongated islands centered around the magnetar DM. Pulses that are farther from that line (e.g., at ∼6200 s) are more likely to be RFIs. Inset: Distribution of pulse S/N as a function of DM. The pink vertical line marks the DM of the magnetar. The distribution of the pulses’ S/N is also centered at the magnetar DM.
