Lynga Open Clusters Catalog: Salient Data for Galactic Star Clusters

A catalog of all known open star clusters in our galaxy, compiled by Gosta Lynga of Lund Observatory. The data results from merging published values and the JDL project, which assessed and derived weighted means for parameters like reddening and distances. This service is provided by NASA's HEASARC.

Use Cases

• Study galactic structure and stellar populations based on cluster distances and reddenings.
• Analyze cluster evolution and properties based on derived turn-off colors.
• Cross-reference and validate open cluster data using the compiled published references.

Strengths

• Aims to include salient data for all known open clusters in the galaxy.
• Data incorporates weighted mean values derived from assessed and weighted published references.
• Provided by the authoritative NASA HEASARC service.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
