DeepDrill ELAIS S1: Spitzer Infrared Catalog for LSST Deep Fields

The DeepDrill ELAIS S1 2-band Catalog contains infrared observations from the Spitzer Space Telescope's Infrared Array Camera (IRAC). The data, part of Program ID 11086 led by P.I. Lacy, covers the ELAIS-S1 Deep Drilling Field in two bands centered on 3.6 um and 4.5 um. This catalog, provided by the National Aeronautics and Space Administration, was last updated in March 2026.

Use Cases

• Training galaxy detection and classification models based on deep infrared observations.
• Cross-matching multi-wavelength astronomical sources using the combined DeepDrill and SERVS survey coverage.
• Preparing data pipelines for LSST Deep Drilling Fields by analyzing precursor infrared data.
• Studying galaxy evolution and structure in deep fields using the 3.6 um and 4.5 um infrared bands.

Strengths

• Observations are from the Spitzer Space Telescope Infrared Array Camera (IRAC), a space-based observatory.
• Data covers the ELAIS-S1 field, one of the defined LSST Deep Drilling Fields.
• Combines with earlier SERVS observations to expand coverage of the LSST DDF footprints.

Limitations

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