DeepDrill CDFS 2-band Catalog: Spitzer IRAC Observations for LSST Deep Drilling Fields

Spitzer Space Telescope infrared observations of three deep sky fields targeted for the Vera C. Rubin Observatory Legacy Survey of Space and Time. The DeepDrill survey used the Infrared Array Camera to observe the Extended Chandra Deep Field-South, ELAIS-S1, and XMM-LSS fields at 3.6 and 4.5 microns, expanding coverage from an earlier SERVS survey. Data is provided by the National Aeronautics and Space Administration and was last updated in March 2026.

Use Cases

• Calibrate and prepare for LSST Deep Drilling Field observations based on prior infrared data.
• Conduct multi-wavelength galaxy studies based on combined DeepDrill and SERVS infrared coverage.
• Analyze source properties in deep extragalactic fields based on 3.6 and 4.5 micron photometry.
• Train machine learning models for source detection and classification in infrared astronomy data.

Strengths

• Observations target three specific, scientifically critical deep fields (ECDFS, ES1, XMM-LSS) for the upcoming LSST.
• Data combines with earlier SERVS survey observations, suggesting a larger combined footprint.
• Data originates from the Spitzer Space Telescope, a major NASA observatory.

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 access and analysis.
