Spitzer Extragalactic First Look Survey: SDSS and MIPS Photometric Catalog

Four square degrees of infrared imaging from the Spitzer Space Telescope, centered at J1718+5930. The 67-hour survey, conducted after Science Verification in November 2003, aimed to characterize extragalactic sources down to sub-millijansky levels. This catalog presents the SDSS and MIPS photometry from Papovich et al. (2006).

Use Cases

• Characterizing extragalactic source populations based on mid-infrared imaging data.
• Cross-matching and analyzing multi-wavelength data based on combined SDSS and MIPS photometry.
• Studying faint astronomical objects based on sub-millijansky sensitivity levels.

Strengths

• Imaging covers 4 square degrees of sky.
• Survey conducted over a dedicated 67-hour observation period.
• Data includes ancillary observations 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 may reflect temporal bias inherent to the specific 2003 observation period.
