Abstract

Polarization-angle density displays were given for pulsars B0809+74 and B2303+30, which exhibited no evidence of the systematic polarization-angle rotation within individual subpulses. The drifting subpulses of both pulsars exhibited linear and circular polarization which appeared to reflect the characteristics of two nearly orthogonally polarized emission modes. PSR B0809+74's subpulses appeared to exhibit the extraordinary PA rotation on the basis of early observation and analytical methods.
