Polarisation profile of J1455−3330 obtained from integrating 32.2 hours of observations with the MeerKAT L-band receiver. The black, red, and blue lines in the top panel indicate the total intensity, linear polarisation fraction, and circular polarisation fraction, respectively. The middle panel shows the evolution of the PA across the pulsar’s phase. The PA exhibits the characteristic swing as well as some phase jumps. The red solid line corresponds to the RVM fit to the PA, and the dashed line shows the RVM solution separated by 90° from the main fit to include the jumped PA values (blue dots). The bottom panel shows the PA residuals.
