VII/202 Globular Clusters in the Milky Way (Harris, 1997)
================================================================================
A catalog of parameters for globular clusters on the Milky Way

ADC_Keywords: Clusters, globular
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.
