/catalogs/3/3097A/
The following is the "ReadMe" document that describes this ADC catalog. You can access the files described here in three ways:
III/97A Radial Velocities in open clusters (Mermilliod 1984)
================================================================================
Bibliography of Individual Radial Velocities for Stars in Open Clusters II.
NGC and IC Clusters
Mermilliod J.C.
<Bull. Inform. CDS 26, 9, (1984)>
=1984BICDS..26....9M
================================================================================
ADC_Keywords: Bibliography; Clusters, open; Radial velocities
Description:
This second part of the bibliography contains 6504 individual
radial velocities for 774 stars in 78 open clusters. It is devoted
to NGC and IC open clusters. The first part (Mermilliod J.-C.,
1979, Bull. Inform. CDS 16,2; catalogue III/55/) contains the
data for five nearby open clusters. The collected data have been
found in the literature published from 1900 to the end of 1983.
This catalog contains also unpublished data which have been
delivered to Mermilliod by several authors.
