Spitzer Extragalactic First Look Survey: MIPS 160 Micron Source Catalog

A 67-hour survey conducted in late 2003, this dataset contains mid-infrared source observations from the Spitzer Space Telescope's MIPS instrument at 160 microns. The Extragalactic First Look Survey covers 4 square degrees of sky, aiming to characterize extragalactic 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 sub-millijansky mid-infrared flux levels.
• Cross-referencing infrared sources with ancillary optical and radio telescope data mentioned in the description.
• Analyzing source density and properties across a 4-square-degree field of view.

Strengths

• Observations were made during the initial Science Verification phase of the Spitzer Space Telescope in late 2003.
• Survey covers a significant 4 square degrees of sky imaging.
• 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 early mission period (late 2003); newer instruments may provide updated observations.
