SAFIRES: Spitzer Far-Infrared Extragalactic Source Catalog

Nearly 1132 fields spanning almost 180 square degrees of sky comprise this catalog of far-infrared sources. The Spitzer Archival Far-Infrared Extragalactic Survey (SAFIRES) applies enhanced processing methods to Spitzer Space Telescope MIPS 70-micron data, funded by a NASA ADAP grant. The sample excludes fields near the Galactic disk and extended sources to maintain high reliability.

Use Cases

• Identify extragalactic point sources based on 70-micron far-infrared flux measurements.
• Study star formation rates in distant galaxies based on far-infrared emission data.
• Cross-match sources with other astronomical catalogs based on the provided sky coordinates for multi-wavelength analysis.
• Analyze the distribution of far-infrared sources across 180 square degrees of high-latitude sky.

Strengths

• Covers nearly 1132 distinct astronomical fields.
• Spans almost 180 square degrees of sky, providing a broad survey area.
• Excludes fields near the Galactic disk to minimize contamination and enhance reliability.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The data format is listed as BIN, which may require specialized tools for access and analysis.
