Query: Correlation of Excursion Sets for Non-Gaussian CMB Temperature
  Distributions   We present a method, based on the correlation function of excursion sets
above a given threshold, to test the Gaussianity of the CMB temperature
fluctuations in the sky. In particular, this method can be applied to
discriminate between standard inflationary scenarios and those producing
non-Gaussianity such as topological defects. We have obtained the normalized
correlation of excursion sets, including different levels of noise, for 2-point
probability density functions constructed from the Gaussian, \chi_n^2 and
Laplace 1-point probability density functions in two different ways.
Considering subdegree angular scales, we find that this method can distinguish
between different distributions even if the corresponding marginal probability
density functions and/or the radiation power spectra are the same.
