Spitzer Extragalactic First Look Survey: IRAC Ch2 Verification Field Catalog

The Extragalactic First Look Survey covers 4 square degrees of infrared imaging centered at J1718+5930. This 67-hour survey, conducted by NASA's Spitzer Space Telescope in late 2003, aimed to characterize extragalactic source populations down to sub-millijansky levels in the mid-infrared.

Use Cases

• Characterizing extragalactic source populations based on mid-infrared imaging.
• Analyzing source density and distribution based on 4 square degrees of survey coverage.
• Cross-referencing infrared data with ancillary optical and radio telescope observations mentioned in the description.

Strengths

• Covers 4 square degrees of imaging, providing a substantial survey area.
• Data was collected during a 67-hour observation period with the Spitzer Space Telescope.
• Includes ancillary data from ground-based optical and radio telescopes.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is from a specific verification period in late 2003; temporal coverage is limited.
