VizieR Online Data Catalog: Seven-year WMAP catalog (Gold+, 2011)

The Wilkinson Microwave Anisotropy Probe (WMAP) was launched in 2001 to observe the cosmic microwave background (CMB). With five frequency bands centered at 23, 33, 41, 61, and 94GHz (respectively, denoted as K, Ka, Q, V, and W bands), full-sky coverage, polarization sensitivity, and control of systematics to the sub-percent level, WMAP is able to measure diffuse (1° and larger) emission with precise temperature calibration. The five-band catalog (table 5) contains 471 sources, the QVW catalog (table 6) contains 417 sources, and the two catalogs have 346 sources in common.
