WMAP Nine-Year CMB-Free QVW Point Source Catalog

502 point sources detected in three microwave frequency bands (41, 61, and 94 GHz) by the Wilkinson Microwave Anisotropy Probe (WMAP). The catalog is based on data from the entire 9-year sky survey from 10 August 2001 to 10 August 2010, using a method to remove cosmic microwave background fluctuations. The data was produced by the National Aeronautics and Space Administration.

Use Cases

• Cross-matching microwave sources with radio catalogs based on the described 5-GHz counterpart identification.
• Analyzing the spectral properties of point sources using the three frequency bands (Q, V, W).
• Studying the spatial distribution of microwave point sources across the all-sky survey.
• Validating source detection algorithms based on the described CMB-free internal linear combination (ILC) method.

Strengths

• Contains 502 point sources, providing a substantial sample for analysis.
• Data spans a 9-year time range from 2001 to 2010, offering temporal stability.
• Sources are identified using a CMB-free method across three frequency bands, enhancing signal clarity.

Limitations

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