DeepDrill CDFS: Infrared Source Catalog for LSST Deep Drilling Fields

The Vera C. Rubin Observatory Legacy Survey of Space and Time (LSST) will observe several Deep Drilling Fields (DDFs). This catalog contains infrared observations at 4.5 microns from the Spitzer Space Telescope's DeepDrill survey, covering three LSST DDFs. The data were produced by the National Aeronautics and Space Administration and last updated in March 2026.

Use Cases

• Training galaxy detection models based on infrared photometry from Spitzer IRAC.
• Cross-matching multi-wavelength sources for the LSST Deep Drilling Fields mentioned in the description.
• Analyzing the extended area coverage from the combined DeepDrill and SERVS surveys.
• Preparing photometric redshift pipelines using 3.6 and 4.5 micron band data.

Strengths

• Observations from the Spitzer Space Telescope Infrared Array Camera (IRAC).
• Covers three defined LSST Deep Drilling Fields: ECDFS, ES1, and XMM-LSS.
• Combines data with the earlier Spitzer Extragalactic Representative Volume Survey (SERVS).

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 BIN and PDF, which may require specialized tools for analysis.
