DeepDrill XMM-LSS: Spitzer IRAC 4.5 Micron Source Catalog

The DeepDrill XMM-LSS 4.5 micron Catalog contains infrared observations from the Spitzer Space Telescope's Infrared Array Camera (IRAC). The data was collected by NASA as part of Program ID 11086 to support the Vera C. Rubin Observatory Legacy Survey of Space and Time (LSST) by observing Deep Drilling Fields. It was last updated on March 13, 2026.

Use Cases

• Identify and catalog distant galaxies based on infrared flux measurements.
• Study the large-scale structure of the universe within the XMM-LSS field.
• Combine infrared data with optical surveys for multi-wavelength object classification.
• Prepare calibration and validation datasets for future Rubin Observatory LSST observations.

Strengths

• Data originates from the Spitzer Space Telescope, a NASA space observatory.
• Observations are coordinated to support the future Vera C. Rubin Observatory LSST.
• Combines coverage with earlier SERVS survey data for a larger footprint.

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.
