Title: Testing global isotropy of three-year Wilkinson Microwave Anisotropy Probe (WMAP) data: Temperature analysis

Abstract

We examine statistical isotropy of large scale anisotropies of the Internal Linear Combination (ILC) map, based on 3 yr WMAP data. Our study reveals no significant deviation from statistical isotropy on large angular scales of the 3 yr ILC map. Comparing statistical isotropy of the 3 yr ILC map and 1 yr ILC map, we find a significant improvement in the 3 yr ILC map which can be due to the gain model, improved ILC map processing, and foreground minimization.
