| # Detailed Description of VII/189 : Catalog of Pulsars (Taylor+ 1995) |

Note : this is the description file of the original catalog. This HTML page corresponds well to the original description, but some minor changes in the format may have been introduced in the FITS output files in order to allow for arithmetic operations on quantities such as coordinates and times. h:m:s and d:m:s units are normally converted into degrees, and YYYY-MM-DD into julian days.
Similarly, some slight changes may have been introduced in the units; the value given in the HTML files supersedes the value indicated in the ReadMe file for this catalogue.

    Description:
        The catalogue is a compilation of the principal observed parameters of
        706 pulsars (updated  from  558  pulsars  in  the  previous  version),
        including positions, timing parameters, pulse widths,  flux densities,
        proper motions, distances,  and dispersion,  rotation,  and scattering
        measures.   It also lists the orbital elements of binary pulsars,  and
        some  commonly used  parameters derived  from the  basic measurements.
        Uncertainties are quoted for most quantities.

    Remarks:
        The files are directly transformed from the computer database
        described in the paper (from node pulsar.princeton.edu) in its status
        of May 3, 1995. The files "table1.dat" (Observed and Derived
        parameters corresponding to tables 1, 2 and 4 of the publication) and
        "table3.dat" (binary pulsar orbital elements) were rebuilt from the
        file "ascat1.dat", the only modifications being the conversion from
        radians to degrees for positional data.

        The files here are NOT regularly updated, and users may want to check
        the Princeton ftp site for updates. The database can be loaded via
        anonymous ftp at Internet node pulsar.princeton.edu = 128.112.131.69
        in directory pub/catalog
