- VII/202 Globular Clusters in the Milky Way (Harris, 1997)
- ================================================================================
- A catalog of parameters for globular clusters on the Milky Way
- Harris W.E.
- <Astron. J. 112, 1487 (1996, rev. 15 May 1997)>
- =1996AJ....112.1487H
- ================================================================================
- 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.
