Search for intrinsic anisotropy in the UHECRs data from the Pierre Auger Observatory

We discuss techniques which have been developed for determining the intrinsic anisotropy of sparse ultra-high-energy cosmic ray datasets, including a two point, an improved two point and a three point method. Monte-Carlo studies of the sensitivities of these tests are presented. We perform a scan in energy above the 100 highest energy events (corresponding to '43 EeV) detected at the Pierre Auger Observatory and find that the largest deviation from isotropic expectations occurs for events above 52 EeV.
