Catalog of 558 Pulsars

We present an up-to-date compilation of the principal observed parameters of 558 pulsars, including positions, timing parameters, pulse widths, flux densities, proper motions, distances, and dispersion, rotation, and scattering measures. We also list the orbital elements of binary pulsars and some commonly used parameters derived from the basic measurements. Uncertainties are quoted for most quantities, and references to the original literature are given. Figures are used to illustrate the sample distributions of some of the more important parameters. Machine-readable versions of the tabulated information are available, together with software designed to make the data base useful to others working in the field.
