ROSAT/XMM-Newton 13-hr Deep Field: 449 Radio Sources at 1.4 GHz

NASA HEASARC provides a catalog of 449 radio sources detected at 1.4 GHz in a 30-arcmin diameter region centered on the ROSAT/XMM-Newton 13-hour deep field. The survey combined 24 hours of Very Large Array data to achieve a 7.5 microJansky noise limit and a 4-sigma detection threshold of 30 uJy at the map center. This table was created in July 2013 based on data from the CDS catalog J/MNRAS/352/131.

Use Cases

• Cross-match radio sources with X-ray catalogs to study multi-wavelength emission mechanisms.
• Analyze the differential source count upturn at sub-milliJansky flux densities to model faint source populations.
• Investigate the composition of the radio source population, comparing star-forming galaxies and active galactic nuclei.
• Use the deep survey's sensitivity and resolution as a benchmark for other 1.4 GHz radio surveys.

Strengths

• Contains a complete sample of 449 sources detected above a 4-sigma threshold.
• Achieves a deep noise limit of 7.5 microJansky and a central detection limit of 30 uJy.
• Covers a 30-arcmin diameter region with 3.35-arcsec resolution from 24 combined hours of VLA data.

Limitations

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