SpUDS IRAC Catalog: Infrared Observations of the UKIDSS Ultra Deep Survey

The UKIDSS Ultra Deep Survey (UDS) is a ~1 square degree area, representing the largest deep near-infrared survey. The Spitzer Public Legacy Survey of the UDS (SpUDS) provides deep infrared observations of this region using IRAC and MIPS instruments, enabling sampling of representative cosmological volumes out to high redshifts (z>6). This dataset is provided by the National Aeronautics and Space Administration and was last updated in March 2026.

Use Cases

• Train models for infrared source detection and classification based on deep IRAC and MIPS observations.
• Analyze galaxy properties and evolution across cosmic time based on observations sampling representative cosmological volumes.
• Conduct cosmological studies of high-redshift (z>6) objects mentioned in the survey description.
• Cross-match infrared sources with other wavelength surveys using the defined ~1 square degree UDS field.

Strengths

• Covers a ~1 square degree survey area, which is described as the largest deep near-infrared survey.
• Observes representative cosmological volumes (100x100 Mpc) out to high redshifts (z>6).
• Data originates from the authoritative source National Aeronautics and Space Administration.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and dataset size are unknown, which may limit suitability assessment.
• File formats include BIN and HTML, which may require specialized tools for access and analysis.
