DeepDrill CDFS: Spitzer IRAC 3.6 Micron Catalog for LSST Deep Drilling Fields

Spitzer Space Telescope infrared observations at 3.6 microns for three of the Vera C. Rubin Observatory's LSST Deep Drilling Fields. The data, collected under Program ID 11086, expands upon earlier SERVS survey coverage in the ECDFS, ES1, and XMM-LSS fields. This catalog was published by the National Aeronautics and Space Administration and was last updated in March 2026.

Use Cases

• Training galaxy detection and classification models based on deep infrared observations.
• Cross-matching and validating multi-wavelength astronomical catalogs for the LSST Deep Drilling Fields.
• Conducting photometric redshift estimation using combined 3.6 and 4.5 micron infrared data.
• Studying galaxy evolution in deep extragalactic fields by leveraging the expanded area coverage.

Strengths

• Data originates from the Spitzer Space Telescope, a major NASA observatory.
• Observations target three specifically defined LSST Deep Drilling Fields (ECDFS, ES1, XMM-LSS).
• Combines with prior SERVS survey data to provide expanded coverage for these critical fields.

Limitations

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