Shakhabazian Compact Groups: 3,435 Galaxies with Positions and Photometry

Southern sky data (delta ≤ +2.5 degrees) provides accurate positions and photometric properties for individual galaxies within compact groups. The catalog contains 3,435 galaxies across 373 groups, derived from the COSMOS/UKST catalog and the CDS Catalog VII/196. NASA HEASARC created this database table in June 2000.

Use Cases

• Classifying galaxy group membership based on accurate positional data.
• Analyzing photometric properties of galaxies in compact groups.
• Studying the structure and distribution of compact galaxy groups in the Southern sky.
• Cross-referencing galaxy data with other astronomical surveys using catalog identifiers.

Strengths

• Contains 3,435 individual galaxies identified as group members.
• Covers 373 distinct compact groups.
• Provides accurate positions and evaluated photometric properties.
• Data is sourced from authoritative catalogs (CDS VII/196, COSMOS/UKST).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is known but specific features per row are not detailed in the metadata.
