7C(G) Survey: 6,262 Compact Radio Sources in the Northern Galactic Plane

A catalog of 6,262 compact radio sources detected at 151 MHz by the Cambridge Low Frequency Synthesis Telescope (CLFST). The survey covers specific regions of the northern Galactic plane with a completeness limit of approximately 0.25 Jy and an rms positional accuracy better than 10 arcseconds. This table was created by NASA's HEASARC in October 2010 based on data from the reference paper.

Use Cases

• Identify and catalog compact radio sources based on the 6,262 entries.
• Study source distribution and density in the northern Galactic plane based on the specified longitude and latitude coverage.
• Analyze flux density characteristics tied to the Roger, Bridle & Costain scale with better than 10% accuracy.
• Cross-match sources with other astronomical surveys using the reported positional accuracy better than 10 arcseconds.

Strengths

• Contains 6,262 compact sources, providing a substantial sample for analysis.
• Has a defined completeness limit of ~0.25 Jy over most of the survey region.
• Reports an rms positional accuracy better than 10 arcseconds.
• Flux densities are tied to a known scale with an accuracy better than 10 percent.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is known, but the specific column names and data types are not provided in the metadata.
