STeVECat: Spectral TeV Extragalactic Catalog from Imaging Cherenkov Telescopes

STeVECat compiles high-level results from three decades of extragalactic very high-energy gamma-ray astronomy. The catalog contains spectral data from imaging atmospheric Cherenkov telescope observations of sources like Markarian 421. It was created by Lucas Gréaux et al. at the Centre National de la Recherche Scientifique and presented at ICRC 2023.

Use Cases

• Modeling spectral energy distributions based on cataloged very high-energy spectra.
• Analyzing source variability and spectral states across different extragalactic objects.
• Training machine learning models for source classification based on spectral features.
• Benchmarking theoretical models against observational data from imaging atmospheric Cherenkov telescopes.

Strengths

• Catalog spans three decades of extragalactic very high-energy observations.
• Includes data from multiple imaging atmospheric Cherenkov telescopes.
• Provides a Python script for data loading, aiding accessibility.

Limitations

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