Polarimetric observations of southern pulsars at 800 and 950 MHz

Polarimetric data are presented for a total of 82 (mostly southern) pulsars at observing frequencies of 800 MHz (18 pulsars) and 950 MHz (82 pulsars). 32 of the sources were observed using a high-speed integrator with milliperiod resolution. for many of the pulsars observed, there is no published po...

Description
Summary:Polarimetric data are presented for a total of 82 (mostly southern) pulsars at observing frequencies of 800 MHz (18 pulsars) and 950 MHz (82 pulsars). 32 of the sources were observed using a high-speed integrator with milliperiod resolution. for many of the pulsars observed, there is no published polarimetry and, for most, these observations constitute the only data between 630 and 1612 MHz. Faraday rotation measurements for 24 pulsars are also presented. Most of the pulsars examined show properties that are readily explicable in terms of core and conal components. Notable results include integrated profile mode-changing identified for the first time in PSR B1358 — 63, confirmation of high inclinations between magnetic and rotation axes in the interpulsars PSR B1055—52 and PSR B1702—19, and significant rotation measure changes in PSR B1556 — 44 and PSR B1727 — 47.
