Spitzer Enhanced Imaging Products: IRAC and MIPS Source List and Coverage

The Spitzer Science Center and Infrared Science Archive released enhanced imaging products from the Spitzer Heritage Archive. These products include mosaic images and a source list of photometry for compact sources from the four IRAC channels (3-8 microns) and the 24-micron MIPS channel. The source list prioritizes reliability over completeness, meaning it is not complete at any flux density.

Use Cases

• Identify reliable compact infrared sources based on the provided source list photometry.
• Verify data existence for specific astronomical regions using the coverage table.
• Perform custom photometry measurements on the provided super mosaics for sources missing from the catalog.

Strengths

• Data products are released by the authoritative Spitzer Science Center and Infrared Science Archive.
• Source list is designed for high reliability, with sources rejected to meet strict criteria.
• Includes data from multiple instruments: four IRAC channels and the 24-micron MIPS channel.

Limitations

• The source list is explicitly not complete at any flux density, prioritizing reliability.
• Row count and dataset size are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
