Polarization-angle density displays are given for pulsars B0809+74 and B2303+30, which exhibit no evidence of the systematic polarization-angle rotation within individual subpulses previously reported for these two stars. The “drifting” subpulses of both pulsars exhibit strikingly linear and circular polarization which appears to reflect the characteristics of two nearly orthogonally polarized emission “modes” – along which the severe average-profile depolarization that is characteristic of their admixture at comparable overall intensities.
Key words: stars: pulsars: B0809+74, B2303+30 / polarisation / radiation mechanisms: non-thermal
