HETE-2: Gamma-Ray Burst Triggers Catalog from NASA HEASARC

HETE-2 (High Energy Transient Explorer) was launched on October 9, 2000, and declared operational on February 6, 2001. The catalog contains triggers for cosmic gamma-ray bursts (GRBs) detected by the satellite's three science instruments: FREGATE, WXM, and SXC. This HEASARC database table is updated twice weekly based on online tables from NASA's Gamma-ray Coordinates Network.

Use Cases

• Analyzing the temporal distribution of gamma-ray bursts based on the trigger timestamps.
• Correlating burst detections across different energy bands (soft X-ray, medium X-ray, gamma-ray) based on the multi-instrument mission design.
• Studying the localization precision of gamma-ray burst sources provided by the HETE-2 mission.

Strengths

• Data is updated twice weekly, providing relatively current observations.
• Based on tables from NASA's Gamma-ray Coordinates Network (GCN), a primary source for GRB alerts.
• Contains data from a dedicated international mission with three complementary science instruments.

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 the temporal and instrumental bias of the HETE-2 mission's operational period.
