VVDS-VLA Deep Field: 610-MHz Radio Source Catalog from GMRT

A catalog of 514 radio sources detected at 610 MHz in a 1-square-degree deep field. The table contains 557 entries, including 17 sources with multiple components, derived from Giant Metrewave Radio Telescope observations with 6-arcsecond resolution. NASA HEASARC created this table in February 2012 based on the CDS catalog J/A+A/463/519.

Use Cases

• Identify and analyze radio source populations based on the 514 cataloged sources.
• Study source morphology and structure based on the 17 sources fitted with multiple components.
• Conduct statistical analysis of source density and distribution across the 1-square-degree field.
• Cross-match radio sources with optical or other wavelength catalogs using the provided J2000 coordinates.

Strengths

• Catalog lists 514 distinct radio sources, providing a substantive sample for analysis.
• Observations cover a 1-square-degree area with a defined angular resolution of 6 arcseconds.
• Includes detailed entries for 17 multiple-component sources, totaling 557 table rows.

Limitations

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