Query: Structure of pulsar beams: conal versus patchy   Structure of mean pulsar radiation patterns is discussed within the
nested-cones and patchy beam models. Observational predictions of both these
models are analyzed and compared with available data on pulsar waveforms. It is
argued that observational properties of pulsar waveforms are highly consistent
with the nested-cone model and, in general, inconsistent with the patchy beam
model.
