ATCA-ADFS: 530 Radio Sources Catalog from the AKARI Deep Field South

A 1.1 deg² region near the South Ecliptic Pole was surveyed at 20 cm wavelength using the Australia Telescope Compact Array. The catalog contains 530 radio sources detected with a resolution of 6.2 x 4.9 arcseconds, based on 170 hours of observations conducted in July 2007 and December 2008. The data were processed by NASA HEASARC in November 2013 from a published astronomical catalog.

Use Cases

• Cross-match radio sources with infrared counterparts based on the described AKARI far-infrared and mid-infrared survey data.
• Analyze source density and distribution for cosmological studies based on the reported 1-sigma detection limits and surveyed area.
• Study radio source morphology and component structure based on the described Gaussian modeling of radio emission.
• Perform statistical analysis of deep radio source counts based on the catalog of 530 detected sources.

Strengths

• Catalog contains 530 identified radio sources with specific positional resolution (6.2 x 4.9 arcseconds).
• Survey has quantified sensitivity limits ranging from 18.7 to 50 microJansky per beam.
• Observations comprise 170 total hours of integration time from two dedicated observing sessions.
• Data is linked to a specific, well-documented astronomical field (AKARI Deep Field South) with complementary infrared observations.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect observational bias inherent to the specific telescope and survey strategy.
