SpUDS MIPS Catalog: Infrared Survey of the UKIDSS Ultra Deep Field

A 2026 catalog from NASA's Spitzer Space Telescope provides infrared observations of the UKIDSS Ultra Deep Survey (UDS) field. The survey consists of deep IRAC and 24 micron MIPS observations covering approximately 1 square degree. The UDS is the largest deep near-infrared (JHK) survey, sampling representative cosmological volumes out to high redshifts (z>6).

Use Cases

• Identify and catalog distant galaxies based on deep infrared observations.
• Study galaxy evolution and star formation history across cosmic time using the survey's deep, wide-field data.
• Conduct cosmological analyses by sampling representative large-scale structures mentioned in the description.
• Cross-match infrared sources with other multi-wavelength datasets for comprehensive object characterization.

Strengths

• Covers a large, approximately 1 square degree deep field, enabling statistical studies.
• Provides data from two Spitzer instruments (IRAC and MIPS) for multi-wavelength analysis.
• Targets the largest existing deep near-infrared survey (UDS), sampling representative cosmological volumes.

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.
• Data is provided in BIN and HTML formats, which may require specialized tools for access and analysis.
