ATESP: 1.4-GHz Radio Source Catalog for the ESO Slice Project Region

A catalog of 2967 radio sources detected at 1.4 GHz by the Australia Telescope Compact Array over a 26-square-degree region of the sky. The survey achieved a uniform sensitivity with a 1-sigma noise level of approximately 79 microJansky and a detection limit of about 0.5 mJy. This table was created by NASA's HEASARC in November 2012 based on data from the CDS catalog.

Use Cases

• Cross-matching radio sources with optical galaxy redshift data from the ESO Slice Project.
• Analyzing the statistical properties of sub-millijansky radio source populations.
• Studying the morphology and multiplicity of radio sources based on the cataloged double, triple, and quadruple components.
• Training models for radio source detection and classification in wide-field surveys.

Strengths

• Contains 2967 radio sources with a reported 1-sigma noise level of ~79 microJansky.
• Covers a 26-square-degree region with uniform sensitivity, providing a consistent sample.
• Includes entries for 169 double, 19 triple, and 2 quadruple sources, detailing composite structures.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The catalog contains a slightly different source count (2967) than the 2960 cited in the reference paper.
