VLA SXDF: 505 Radio Sources with Optical/Near-IR Counterparts and Redshifts

A catalog of 505 radio sources with 1.4-GHz flux densities greater than 100 microjanskys over a 0.81 square-degree region of the Subaru/XMM-Newton Deep Field. The dataset, created by the NASA HEASARC in August 2013, provides spectroscopic and 11-band photometric redshifts for the galaxies in this sample, analyzing their infrared-radio correlation and stellar population properties.

Use Cases

• Classifying radio-loud versus radio-quiet galaxies based on the infrared-radio correlation described in the study.
• Analyzing the relationship between K-band magnitude and radio flux density for sources below ~1 mJy.
• Testing redshift distribution predictions against models like the Square Kilometre Array Simulated Skies project.
• Studying spectral energy distributions of radio hosts to infer stellar population ages.

Strengths

• Contains 505 distinct radio sources with flux densities above 100 microjanskys.
• Covers a 0.81 square-degree survey area, providing a focused deep-field sample.
• Includes both spectroscopic and 11-band photometric redshift estimates for analysis.
• Integrates data from multiple observational campaigns and instruments like VIMOS and UKIRT.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
