CGRO/BATSE 4B Catalog: 1,637 Gamma-Ray Bursts from 1991-1996

1,637 triggered gamma-ray bursts observed by the Compton Gamma-Ray Observatory (CGRO) between 19 April 1991 and 29 August 1996. The catalog includes data from the previous 3B catalog with improved locations for three specific triggers. NASA's HEASARC created this database table in March 1999 based on data from the CGRO Science Support Center.

Use Cases

• Analyze gamma-ray burst temporal distribution based on the 5-year observation period mentioned in the description
• Study burst location accuracy improvements based on the revised positions for three specific triggers
• Investigate data gap effects on flux and duration measurements based on the described recorder error periods
• Compare location methodologies based on the described MAXBC rates versus other data types

Strengths

• Contains 1,637 distinct gamma-ray burst observations
• Covers a 5-year time span from 1991 to 1996
• Includes improved locations for three specific bursts from the previous catalog

Limitations

• Data gaps for many bursts preclude valid measurement of peak flux, peak rate, fluence, or duration
• MAXBC-located bursts usually have larger statistical errors than bursts located with other data types
• Column-level documentation is absent; field semantics must be inferred after download
