Spitzer Extragalactic First Look Survey: Infrared Source Catalog

A 67-hour survey conducted with the Spitzer Space Telescope's IRAC and MIPS instruments in November 2003. The Extragalactic First Look Survey covers 4 square degrees centered at J1718+5930, aiming to characterize mid-infrared source populations down to sub-millijansky levels. It was produced by the National Aeronautics and Space Administration (NASA).

Use Cases

• Characterizing extragalactic source populations based on mid-infrared imaging.
• Analyzing source density and properties down to sub-millijansky flux levels.
• Cross-referencing infrared sources with ancillary optical and radio telescope data mentioned in the description.

Strengths

• Data originates from a dedicated 67-hour survey with the Spitzer Space Telescope.
• Covers a 4 square degree field with imaging from both IRAC and MIPS instruments.
• 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.
