Query: Foreground contamination of the WMAP CMB maps from the perspective of
  the matched circle test   WMAP has provided CMB maps of the full sky. The raw data is subject to
foreground contamination, in particular near to the Galactic plane. Foreground
cleaned maps have been derived, e.g., the internal linear combination (ILC) map
of Bennett et al. and the reduced foreground TOH map of Tegmark et al. Using S
statistics we examine whether residual foreground contamination is left over in
the foreground cleaned maps. In particular, we specify which parts of the
foreground cleaned maps are sufficiently accurate for the circle-in-the-sky
signature. We generalise the S statistic, called D statistic, such that the
circle test can deal with CMB maps in which the contaminated regions of the sky
are excluded with masks.
