Spitzer Extragalactic First Look Survey: MIPS 70-Micron Source Catalog

The Extragalactic First Look Survey covers 4 square degrees of imaging centered at J1718+5930. This 67-hour survey, conducted with the Spitzer Space Telescope's MIPS and IRAC instruments after Science Verification in November 2003, aimed to characterize extragalactic sources down to sub-millijansky levels in the mid-infrared. The dataset is provided by the National Aeronautics and Space Administration.

Use Cases

• Characterizing extragalactic source populations based on mid-infrared imaging.
• Analyzing source properties at sub-millijansky flux levels based on Spitzer MIPS observations.
• Cross-referencing infrared sources with ancillary optical and radio data mentioned in the description.

Strengths

• Data from the Spitzer Space Telescope, a major NASA observatory.
• Survey covers 4 square degrees of sky with a dedicated 67-hour observation.
• 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 was collected in late 2003; newer infrared surveys may exist.
