XMM-Newton X-Ray Sources in the Canada-France Redshift Survey Fields

July 2005 saw the creation of this catalog of X-ray sources from XMM-Newton satellite surveys of the 3-h and 14-h fields in the Canada-France Redshift Survey. The table contains sources in the 0.5-10 keV flux range from ~2e-15 to 1e-13 erg/cm²/s, with optical identifications for 79% of sources where deep images were available. It was created by NASA's HEASARC based on published tables from the Monthly Notices of the Royal Astronomical Society.

Use Cases

• Cross-matching X-ray and optical sources based on the described identification methodology.
• Analyzing the redshift distribution of X-ray sources, which the description notes has a strong peak at z~0.7.
• Studying the properties of optically faint, high-redshift sources, which are noted as likely lacking identifications.
• Calibrating photometric redshift estimation methods using the described spectroscopic redshift calibration sample of ~200 galaxies.

Strengths

• Optical identifications are provided for 79% of the XMM-Newton sources with deep optical images.
• Photometric redshift estimates are calibrated using a sample of ~200 galaxies with known spectroscopic redshifts.
• Covers a specific flux range (0.5-10 keV, ~2e-15 to 1e-13 erg/cm²/s) for X-ray sources.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The data is based on a 2005 creation date; freshness should be verified for current research.
