CGRO/BATSE 5B: Gamma-Ray Burst Spectral Catalog with 19,000+ Fits

The CGRO/BATSE 5B Gamma-Ray Burst Spectral Catalog contains results from systematic spectral analyses of 2,145 gamma-ray bursts detected by the Burst and Transient Source Experiment over nine years. It is an official product from the BATSE Science Team, providing a compendium of over 19,000 spectra fitted with five different empirical models. The data files containing complete results are associated with the HEASARC archive.

Use Cases

• Analyzing gamma-ray burst spectral shapes based on the five fitted models (Power law, Comptonized, Band, etc.)
• Comparing peak flux and fluence spectra for bursts based on the 'pflx' and 'flnc' categories
• Studying parameter distributions from systematic fits to understand burst populations
• Validating spectral models using the provided goodness-of-fit measures and energy-resolved quantities

Strengths

• Contains spectral fits for 2,145 distinct gamma-ray bursts
• Offers a compendium of over 19,000 spectra from systematic analysis
• Provides results from five different spectral models selected for empirical importance
• Data is an official product from the BATSE Science Team with detailed procedures documented

Limitations

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