Abstract:
    We measured a sample of 150 pulsar rotation measures (RMs) using the
    20-cm receiver of the Parkes 64-m radio telescope. 46 of the pulsars
    in our sample have not had their RM values previously published,
    whereas 104 pulsar RMs have been revised. We used a novel quadratic
    fitting algorithm to obtain an accurate RM from the calibrated
    polarization profiles recorded across 256MHz of receiver bandwidth.
    The new data are used in conjunction with previously known dispersion
    measures and the NE2001 electron-density model to study models of the
    direction and magnitude of the Galactic magnetic field.

Description:
    We observed a sample of 239 pulsars with the 20-cm H-OH receiver of
    the Parkes 64-m radio telescope in order to obtain a polarization data
    base at high time resolution for all these objects. The observing
    session was carried out from 2006 August 24 to 27.
