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:
    This catalog compiled by William E. Harris contains basic parameters
    on distances, velocities, metallicities, luminosities, colors, and
    dynamical parameters for 147 objects regarded as globular clusters in
    the Milky Way galaxy. A complete list of source references is given in
    the companion file "sources".

    The original files are also accessible through WorldWideWeb, at URL
    http://www.physics.mcmaster.ca/Globular.html

    This version corresponds to revision: May 15, 1997,
      and supersedes the previous version (Catalog VII/195).

Important Notice:
    Please acknowledge the use of this catalog in any published work you
    derive from it. I would also greatly appreciate receiving any new
    information, in published or preprint form, which would help me keep
    the list up to date.
