Gamma-Ray Source Summary Catalog: Master List of Detected Point Sources Circa 2000

420 gamma-ray point sources are listed in this master catalog, combining entries from the original General Gamma-Ray Source Catalog and subsequent updates. The HEASARC at NASA created this database table in March 2001 based on tables supplied by the catalog authors, D. Macomb and N. Gehrels. It serves as a summary list of all detected gamma-ray point sources as of around the year 2000.

Use Cases

• Cross-referencing gamma-ray source detections based on the consolidated master list.
• Studying the distribution and identification of gamma-ray point sources circa 2000.
• Validating source entries against the more detailed Gamma-Ray Source Detailed Catalog (MGGAMMADET).

Strengths

• Consolidates 420 sources from multiple authoritative catalogs (Macomb & Gehrels 1999, 3EG catalog, and HEASARC additions).
• Created and maintained by NASA's HEASARC, an authoritative source for high-energy astrophysics data.
• Explicitly documents the provenance of included sources, noting additions and corrections.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Data reflects the state of detection circa 2000; newer discoveries are not included.
• Row count is unknown, which may limit suitability assessment.
