SpIES Dual-band Catalog: Infrared Source Catalog from Spitzer Telescope Survey

A 115 square degree survey of the Equatorial SDSS Stripe 82 field conducted by the Spitzer Space Telescope. The catalog contains 5.4 million sources detected in both the 3.6 and 4.5 micron infrared bands, with additional single-band catalogs for 6.1 million and 6.4 million sources. It was produced by the National Aeronautics and Space Administration and last updated in March 2026.

Use Cases

• Cross-match infrared sources with optical catalogs based on the defined equatorial survey field.
• Analyze source density and distribution across a large area based on the 115 square degree coverage.
• Train models for infrared source detection and classification based on the dual-band flux measurements.
• Study the photometric properties of astronomical objects using the provided 3.6 and 4.5 micron depth specifications.

Strengths

• Large-scale coverage of 115 square degrees in a well-studied equatorial field.
• Contains a substantial number of sources, with 5.4 million dual-band detections.
• Provides specific depth measurements: 6.13 microJy at 3.6 microns and 5.75 microJy at 4.5 microns.

Limitations

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