Many of our new results favour a conal geometry for the arrangement of emission regions and allow accurate estimates of the emission heights and polar cap locations for the emission cones to be obtained. These results indicate that pulsar emission cones may be located at around half-way out the edge of the polar cap and at altitudes of a few hundred to a thousand kilometers above the neutron star surface. ...
