In this study, Faraday rotation measure (RM) values derived from Arecibo dual-frequency pulsar polarimetry programmes are presented, along with 60 Stokes-profile obtained. RM measurements were conducted towards the inner Galaxy and the anticentre on pulsars with no previous determination, while others were remeasurements to improve accuracy. Profiles were displayed for pulsars without meaningful lower frequency profiles and for those without high-frequency pairs, including distant pulsars in the inner Galaxy. Some polarized pulse profiles showed clear interstellar-scattering tails; nevertheless, attempts were made to interpret emission-beam structures and provide morphological classifications and geometrical models where possible.
We present Faraday rotation measure (RM) values derived at L and P bands as well as some 60 Stokes-parameter profiles, both determined from our long-standing Arecibo dual-frequency pulsar polarimetry programmes. Many of the RM measurements were carried out towards the inner Galaxy and the anticentre on pulsars with no previous determination, while others are remeasurements intended to confirm or improve the accuracy of existing values. Stokes-parameter profiles are displayed for the 58 pulsars for which no meaningful Stokes profile at lower frequency is available and 4 without a high-frequency pair. This is a population that includes many distant pulsars in the inner Galaxy. A number of these polarized pulse profiles exhibit clear interstellar-scattering tails; none the less, we have attempted to interpret the associated emission-beam structures and to provide morphological classifications and geometrical models where possible.
