BDA Open Cluster Database
An earlier and relatively extensive database supervised by Jean-Claude Mermilliod.
Provides information in somewhat different formats than this one;
differences in content and listings may exist between them. Whether working
with this database or the BDA database, researchers will necessarily need to
understand the sources of the data they are using.
A handy link to the
BDA database listing of clusters within 1000 pc. For in-depth studies,
one should review material available on these clusters rather than directly
quoting/applying numbers quoted in table, as more recent work may provide improved
values.
