Detection of periodic signal from the pulsar J0533−4524 (Oostrum et al. 2020) before (left) and after (right) using RFIClean. The lower panels show a stack of partial average profiles obtained by folding over the pulsar’s period, with each row corresponding to about 80 s of data, and the darker colors indicate higher intensities. The upper panels display the vertical averages of data displayed in the lower panels, and correspond to the net average profile of the pulsar. Improvement in the detection significance of the pulsed periodic emission is clearly visible.
