Spitzer Extragalactic First Look Survey: MIPS 24 Micron Extended Source Catalog

An extragalactic source catalog from the Spitzer Space Telescope's First Look Survey, covering 4 square degrees of sky. The survey, conducted for 67 hours in late 2003, aimed to characterize mid-infrared source populations down to sub-millijansky levels using MIPS and IRAC instruments. It was produced by the National Aeronautics and Space Administration.

Use Cases

• Characterize extragalactic source populations based on mid-infrared observations mentioned in the description.
• Analyze galaxy properties and evolution based on sub-millijansky level infrared data.
• Cross-reference astronomical objects using the survey's extensive ancillary optical and radio data.
• Study the mid-infrared sky as observed by one of Spitzer's first major surveys.

Strengths

• Survey covers a defined 4 square degree area of sky.
• Observations were conducted over a dedicated 67-hour period.
• Includes extensive ancillary data from ground-based optical and radio telescopes.
• Aims for sensitive detection down to sub-millijansky levels.

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 2003 survey; newer instruments may provide more recent observations.
