MUSYC: Photometric Redshift Catalog for the Extended Chandra Deep Field South

The Multiwavelength Survey by Yale-Chile (MUSYC) catalog provides photometric redshift data from deep optical and near-IR imaging. The survey covers the ~30'x30' Extended Chandra Deep Field South, which includes the GOODS-South and Hubble Ultra Deep Field regions. The dataset is hosted by the National Aeronautics and Space Administration and was last updated on 2026-03-13.

Use Cases

• Train photometric redshift estimation models based on multiwavelength optical and near-IR photometry.
• Conduct galaxy population studies based on deep-field imaging covering the GOODS-South and Hubble Ultra Deep Field.
• Cross-match and correlate data with other surveys covering the same area, such as the SIMPLE Spitzer Legacy program.

Strengths

• Covers a scientifically significant ~30'x30' field that includes the Hubble Ultra Deep Field.
• Integrates data from multiple wavelengths, including optical medium-band and broadband and near-IR imaging.
• Last updated on 2026-03-13, suggesting recent maintenance.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
