Measuring High Moments of Galaxy Angular Distribution in the First Look Survey using Infrared Array Camera

We present the results of using three methods, the probability distribution function, the Renyi information, and the multi-fractals, to measure the high moments of galaxy angular distribution in the Infrared Array Camera data of the Spitzer First Look Survey. This is the first time that Renyi information is explicitly used to describe the large-scale galaxy spatial distribution, and our galaxy samples are also the first of the kind in their wavelengths and sensitivities.
