SEP Multiwavelength Photometric Catalog: Extragalactic Survey in the South Ecliptic Pole

A multiwavelength photometric catalog from the Spitzer-IRAC/MIPS Extragalactic survey (SIMES) covering a 7.74 square degree area in the South Ecliptic Pole field. The catalog includes flux data from WFI-Rc, MIPS-24 micron, and SPIRE 250, 350, and 500 micron bands, with counterparts identified via nearest-neighbor search. It was produced by the National Aeronautics and Space Administration and was last updated in March 2026.

Use Cases

• Identify extragalactic counterparts based on multiwavelength flux data from WFI-Rc and Spitzer instruments.
• Study galaxy properties and star formation rates using the 3.6 and 4.5 micron depth and completeness limits.
• Analyze the infrared spectral energy distribution of sources using the combined MIPS-24 and SPIRE 250/350/500 micron fluxes.
• Conduct statistical analyses of source populations in a 7.74 square degree survey area of the South Ecliptic Pole.

Strengths

• Survey covers a specific 7.74 square degree area in the South Ecliptic Pole field.
• Provides depth measurements: ~5.80 microJy at 3.6 microns and 5.25 microJy at 4.5 microns (3sigma).
• Includes defined 90% and 50% completeness limits at 14 and 9 microJy, respectively.
• Combines photometric data from multiple instruments (WFI-Rc, MIPS, SPIRE) for cross-wavelength analysis.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is provided in a BIN file format, which may require specialized tools for access and analysis.
