Spitzer Extragalactic First Look Survey: IRAC Ch4 Main Field Catalog

67 hours of Spitzer Space Telescope observations characterize extragalactic source populations down to sub-millijansky levels in the mid-infrared. The Extragalactic First Look Survey covers 4 square degrees of imaging with MIPS and IRAC instruments, centered at J1718+5930. This catalog was produced by NASA as one of the first observations after Science Verification in November 2003.

Use Cases

• Characterize extragalactic source populations based on mid-infrared imaging.
• Cross-match infrared sources with ancillary optical and radio telescope data mentioned in the description.
• Study faint astronomical objects based on sub-millijansky sensitivity levels.

Strengths

• Observations span 67 hours, providing a substantial integration time.
• Covers a 4 square degree field of view for a wide-area survey.
• 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 formats include BIN, which may require specialized tools to read.
