Spitzer South Ecliptic Pole MIPS 24 Micron Point Source Catalog

A point source catalog from Spitzer Space Telescope MIPS 24 and 70 micron imaging of an 11.5 square degree region near the South Ecliptic Pole. The data was processed with APEX software within the MOPEX package, with reliable detections defined as source candidates with S/N > 5 and reduced chi-squared values less than or equal to three. The catalog was produced by the National Aeronautics and Space Administration and was last updated in March 2026.

Use Cases

• Cross-match galaxies with sub-millimeter observations from BLAST based on the complementary wavelength coverage mentioned in the description
• Characterize the properties of infrared-detected galaxies based on the 24 and 70 micron flux data
• Identify and filter potential false positive sources based on the flagged status field described in the catalog
• Support multi-wavelength analysis for the Herschel Multi-tiered Extragalactic Survey (HerMES) field based on the extensive mapping mentioned

Strengths

• Covers an 11.5 square degree region of sky, providing a substantial survey area
• Sources are filtered for reliability with S/N > 5 and specific chi-squared criteria, covering 97% of the catalog
• Complementary to sub-millimeter observations from BLAST and part of a multi-wavelength mapping effort including HerMES

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment for large-scale statistical analysis
