Scientific paper
The basic emission geometry of pulsar B0809+74 is modeled after determinating its polarization position-angle traverse. As the star's profiles are truncated by "absorption" over a broad band, most severely between some 60 and 1500 MHz, the analysis also provides quantitative estimates of the extent of this effect at each frequency. The model's predicted scales are found to agree closely with those determined by correlating pulse sequences observed simultaneously in different bands and by measuring P2 at different frequencies.
