Properties of the known PSR J2227+3038 detected in the TULIPP survey. Upper: polarisation pulse profile obtained from a 20-min observation at a centre frequency of 149 MHz with a 78 MHz bandwidth and 1024 pulse profile bins, showing the normalised flux density (arbitrary units) for total intensity (Stokes I, black line), linear polarisation (L, red dashed line), circular polarisation (Stokes V, blue dotted line), and polarisation position angle (arbitrary average offset from 0 deg). Lower: faraday spectrum (original – grey line; RM CLEANed – black line) computed using PSR J2227+3038 pulsar data. The grey dashed line shows the RM CLEAN component at −59.04 ± 0.03 rad m⁻², prior to the ionospheric RM subtraction.
