GMRT ELAIS-N2 Field: 1,310 Radio Sources Cataloged at 610 MHz

1,310 radio sources detected above a 6-sigma threshold in the ELAIS-N2 field. The catalog is based on observations covering ~6 square degrees at 610 MHz with the Giant Metrewave Radio Telescope, with a resolution of 6.5 x 5 arcsec. This table was created by NASA's HEASARC in February 2012 from source data provided by the University of Cambridge Astrophysics Group.

Use Cases

• Cross-matching radio sources with infrared counterparts based on the survey's complementary nature to existing infrared data.
• Analyzing source density and distribution based on the catalog's coverage of ~6 square degrees.
• Training models for radio source detection based on the 6-sigma detection threshold and noise characteristics.
• Studying telescope performance and survey completeness based on the specified resolution and noise levels.

Strengths

• Catalog contains 1,310 distinct radio sources, providing a substantial sample for analysis.
• Observations cover a significant area of ~6 square degrees with a defined resolution of 6.5 x 5 arcsec.
• Data originates from a major instrument (Giant Metrewave Radio Telescope) and is hosted by NASA HEASARC.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is known (1310), but the specific features and data types per source are unknown from the metadata.
