Spitzer Extragalactic First Look Survey: IRAC Ch1 Verification Field Catalog

The Extragalactic First Look Survey covers 4 square degrees of 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. It includes data from the MIPS and IRAC instruments, supplemented by ancillary ground-based optical and radio observations.

Use Cases

• Characterizing extragalactic source populations based on mid-infrared imaging data.
• Cross-matching infrared sources with ancillary optical and radio telescope data.
• Analyzing source density and flux distributions down to sub-millijansky sensitivity levels.

Strengths

• Data from the Spitzer Space Telescope's early Science Verification period in late 2003.
• Survey covers 4 square degrees of sky with a dedicated 67-hour observation time.
• Includes ancillary data from multiple 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.
