Abstract

Stokes tomography reveals that ≳60 per cent of radio pulsars with superficially dipole-like characteristics (e.g. S-shaped position angle swing; pulse width-period relation) exhibit Q - U phase portraits inconsistent with low-altitude emission in the rotating vector model. It is shown that an offset dipole offers one way to account for the discrepancy for a range of dipole displacement vectors without distorting greatly the pulse shape and position angle swing. © 2014 The Authors Published by Oxford University Press on behalf of the Royal Astronomical Society.
