1.0 Variable Star Catalog

The Variable Star Catalog interface returns summaries of variable stars which satisfy user-defined criteria. The summaries provide hot-click access to a web lightcurve browser and hot-click selection for later ftp download of variable star lightcurve datasets.

2.0 Links to Documentation

Embedded are links to the help pages available during each phase of lightcurve query, selection, and browsing.

3.2 Sample Result: Variable Star Selection

Your query was (RARad_x100K>=130864)and(RARad_x100K<=132028) and (DecRad_x100K>=-121765)and(DecRad_x100K<=-120602).

Warning

The current classifications have been made in an automated manner. Most light curves displayed when selecting a particular classification will belong to that class, but there will be contamination by non-members (primarily binaries).
