SAFIRES: Spitzer Archival Far-Infrared Extragalactic Survey Catalog

The Spitzer Archival FIR Extragalactic Survey (SAFIRES) is a far-infrared source catalog derived from Spitzer Space Telescope data. It contains measurements from the MIPS 70 and 160 micron bands, covering nearly 1132 fields spanning almost 180 square degrees of sky. The dataset was produced by NASA through an Astrophysics Data Analysis Program grant to ensure high reliability by excluding fields near the Galactic disk.

Use Cases

• Identify and catalog far-infrared sources based on MIPS 70 and 160 micron band observations.
• Study extragalactic populations by analyzing a sample that excludes fields near the Galactic disk.
• Conduct statistical analyses of source distributions across nearly 1132 fields covering 180 square degrees.
• Compare source properties with other surveys, leveraging the dataset's focus on point sources (no extended sources).

Strengths

• Covers a significant area of almost 180 square degrees of sky.
• Comprises observations from nearly 1132 distinct fields.
• Designed for high reliability by excluding fields near the Galactic disk to avoid contamination.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for specific modeling tasks.
• The description does not specify the exact time range of the observations.
