Abstract:
We update the systematic studies of circular polarization in
integrated pulse profiles by Han et al. (1998MNRAS.300..373H 1998MNRAS.300..373H). Data of
circular polarization profiles are compiled. Sense reversals can occur
in core or cone components, or near the intersection between
components. The correlation between the sense of circular polarization
and the sense of position angle variation for conal-double pulsars is
confirmed with a much large database. Circular polarization of some
pulsars has clear changes with frequency. Circular polarization of
millisecond pulsars is marginally different from that of normal
pulsars.

dec = decreasing PA
inc = increasing PA
xx = uncertain cases
i+d = change PA variation
d+i = change PA variation
