N2 - We examine the distribution in the arrival directions of the highest energy cosmic rays observed by the Pierre Auger Observatory and Telescope Array using spherical harmonics. We take advantage of the highly anisotropic distribution of matter within the Greisen-Zatsepin-Kuzmin horizon as observed by the 2MASS Redshift Survey coupled with the relatively small deflections expected for protons from current models of the Galactic magnetic field to constrain the likelihood of different nuclear compositions of the UHECR flux.
