Pulsar candidate diagnostic plots: “accn_curve” shows the signal-to-noise ratio as a function of acceleration, “dm_curve” illustrates changes in signal-to-noise across dispersion measure values, “pdm_snr” visualizes the folded signal-to-noise ratio across trial period corrections and DM values, “profile” displays the pulse shape of the candidate, “sub-bands” reveals frequency-dependent signal variations, and “subintegrations” demonstrates time-dependent signal fluctuations.
