AKARI NEP WSRT 20-cm Source Catalog: 462 Radio Sources

A 2004 deep radio survey of the AKARI north ecliptic pole field, covering approximately 1.7 square degrees, produced this catalog of 462 sources. The survey used the Westerbork Radio Synthesis Telescope, achieving a sensitivity as low as 21 microJanskies/beam at 1.4 GHz. This table was created by the NASA HEASARC in March 2011 based on the CDS catalog J/A+A/517/A54.

Use Cases

• Study the redshift evolution of the radio source luminosity function based on deep radio observations.
• Analyze the clustering environment of radio galaxies mentioned in the description.
• Investigate the nature of obscured radio-loud active galactic nuclei (AGN) using the cataloged sources.
• Examine the radio/far-infrared correlation for distant galaxies as referenced in the scientific objectives.
• Perform source identification and morphology analysis for future papers as described.

Strengths

• Catalog contains 462 detected radio sources.
• Survey achieved a deep sensitivity of 21 microJanskies/beam at 1.4 GHz.
• Covers a field of approximately 1.7 square degrees with consistent central sensitivity.

Limitations

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