DeepDrill: Multi-Band Forced Photometry Catalog for ~1.5 Million Sources

The DeepDrill team presents a catalog of multi-band forced photometry in the CDFS and XMM-LSS fields. It contains approximately 1.5 million sources covering a total area of about 9 square degrees. The catalog was produced using The Tractor image-modeling software to deliver de-blended photometry and photometric redshifts across 13 to 15 optical/infrared bands.

Use Cases

• Train photometric redshift estimation models based on the 13-15 optical/infrared band photometry.
• Conduct galaxy population studies based on the catalog of ~1.5 million sources.
• Analyze source properties in specific deep fields (CDFS and XMM-LSS) based on the forced photometry data.
• Benchmark de-blending and image-modeling algorithms against the Tractor-derived photometry.

Strengths

• Covers approximately 1.5 million astronomical sources.
• Spans a significant survey area of about 9 square degrees.
• Provides multi-wavelength data across 13 to 15 optical and infrared bands.
• Includes derived photometric redshifts for sources.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic/temporal/source bias inherent to the specific survey fields.
