Abstract

To compare an anisotropy pattern with theoretical predictions requires a variable that reflects such pattern. For the Cosmic Microwave Background anisotropies it is used a two point correlation function of the radiation temperature, expanded in spherical harmonics. The expansion coefficients values allow a direct comparison between theoretical predictions and experimental data regarding the anisotropic pattern in different scales. How such analysis is done is the main objective of this project. (AU)
