XMM-Newton Optical Monitor UV Catalog for Chandra Deep Field-South

NASA HEASARC provides a UV catalog of 1,129 sources in the Chandra Deep Field-South, created in June 2015. The data originates from the XMM-Newton Optical Monitor's repeated observations between 2001 and 2010. This catalog fills the UV spectral coverage between optical surveys and GALEX observations, with stacking techniques extending detection limits.

Use Cases

• Cross-matching and validating sources based on cross-identification with the ESO Imaging Survey and COMBO-17 surveys mentioned in the description.
• Analyzing multi-wavelength properties of sources using the included optical/UV/X-ray photometric and spectroscopic information from other surveys.
• Studying faint UV sources based on the stacked exposure images that contributed 30% of the catalogued sources.
• Investigating intermediate sources like optically diluted or X-ray absorbed AGN using the combined COMBO-17/X-ray classification discussed.

Strengths

• Contains photometric data for 1,129 CDFS sources in the main catalog.
• Stacking of exposure images extended detection limits by approximately 1 magnitude in three UV bands.
• Sources were validated through cross-identification with established surveys (ESO Imaging Survey, COMBO-17).

Limitations

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