Hubble Ultra Deep Field: 10,040+ Astronomical Source Catalog

A catalog of 10,040 sources identified in the deepest i-band image from the Hubble Ultra Deep Field (UDF) program. The dataset includes an additional 100 manually added sources and 39 sources detected in the z-band, compiled by NASA HEASARC in May 2005. Observations were conducted by the Hubble Space Telescope from September 2003 to January 2004.

Use Cases

• Analyze galaxy populations and distributions based on source detections in the i-band.
• Study faint astronomical objects based on the catalog's inclusion of manually identified sources missed by automated extraction.
• Cross-match multi-wavelength data using source IDs and the four-filter observation strategy (B, V, i, z).
• Validate and improve source detection algorithms by examining the handling of spurious and blended sources.

Strengths

• Formal catalog contains 10,040 sources with detailed provenance.
• Includes manually curated additions for 100 missed sources and 39 z-band detected sources.
• Observations span 400 orbits over 4 months with specific exposure times and AB magnitude zero-points documented.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count for the full table is unknown, which may limit suitability assessment.
