Kommers et al. (2001): 873 Non-Triggered Gamma-Ray Bursts from BATSE

873 gamma-ray bursts detected in archival BATSE satellite data between 1991 and 1997 that were too faint to trigger the on-board system. The catalog, created by NASA HEASARC in 2001, provides estimated source direction, duration, peak flux, and fluence for each event, increasing the total number of BATSE-detected GRBs by 48% for its time period.

Use Cases

• Analyzing the population of faint gamma-ray bursts based on estimated fluence and peak flux.
• Studying burst duration distributions and classifications based on the duration parameter.
• Modeling detection thresholds and instrument sensitivity based on the non-triggered detection method.
• Investigating celestial source directions for spatial distribution analysis.

Strengths

• Contains 873 specific astrophysical events.
• Increases the known BATSE GRB count by 48% for its covered period.
• Provides four key physical parameters (direction, duration, peak flux, fluence) per event.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect temporal bias inherent to the 1991-1997 recording period.
