Timing Parameters of 29 Pulsars

Abstract:  We summarize observations of 29 slow pulsars discovered in recent surveys at Arecibo Observatory. Our sample includes some of the least luminous pulsars known, and forms a group of objects that generally have lower spin-down energy loss rates than the bulk of the population. By measuring pulse times of arrival over spans of one year or more, we have derived precise spin and astrometric parameters for each object. In addition, we present values of dispersion measure, pulse width, and flux density, and we display pulse shapes. We tabulate some derived parameters and discuss objects of particular interest, including one with mode changes, one with significant scattering, and one with the longest known pulse period. We also discuss implications for the scale height of the free electron distribution from the observed distribution of DM sin jbj. Subject headings: ISM: general --- pulsars: general 1.
