Gamma-Ray Source Detailed Catalog: 314 Discrete Sources (Macomb & Gehrels 1999)

314 discrete gamma-ray sources are listed with detailed observations from 50 keV to ~1 TeV. The data is a slightly revised compilation from Tables 2A-2G of the General Gamma-Ray Source Catalog, representing knowledge as of early 1999. This database table was created by NASA's HEASARC in March 2002 based on machine-readable files supplied by the authors.

Use Cases

• Cross-reference gamma-ray source observations based on the listed energy range and source positions.
• Study the observational history of specific sources like A0620-00 or H1822-000 mentioned in the description.
• Compile a historical catalog of gamma-ray detections prior to 1999 for legacy analysis.

Strengths

• Includes 314 discrete sources, reconciling published tables to include 4 previously omitted entries.
• Covers a broad energy range from 50 keV to approximately 1 TeV.
• Originates from a peer-reviewed catalog (Macomb & Gehrels 1999) and was processed by NASA HEASARC.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data reflects knowledge as of early 1999; newer discoveries are not included.
