Spitzer Extragalactic First Look Survey: IRAC Ch2 Main Field Catalog

The Spitzer Extragalactic First Look Survey catalog contains mid-infrared imaging data from the Spitzer Space Telescope. The 67-hour survey, conducted in late 2003, covers 4 square degrees centered at J1718+5930 and aims to characterize extragalactic sources down to sub-millijansky levels. The dataset is provided by the National Aeronautics and Space Administration and includes ancillary ground-based optical and radio data.

Use Cases

• Characterizing extragalactic source populations based on mid-infrared imaging data.
• Cross-matching infrared sources with ancillary optical and radio telescope data.
• Analyzing the properties of faint, sub-millijansky level astronomical objects.
• Studying early Spitzer Space Telescope observations for instrument performance verification.

Strengths

• Covers a 4 square degree field of view for statistical analysis.
• Includes ancillary data from ground-based optical and radio telescopes.
• Aims for deep sensitivity, targeting sub-millijansky flux levels.

Limitations

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