Using a sample of 162 Lyman Alpha emitting galaxies (LAEs) at z=3.1 discovered by the MUSYC collaboration (Gronwall et al. 2007), we analyze photometric properties of stacked galaxy images. We also analyze the photometry of stacked sub-samples published by Lai et al. (2008) that are either detected or undetected in the Spitzer-IRAC 3.6 micron band. Obtaining photometry on stacked images of these samples helps to reveal characteristics of our universe at high redshift via Spectral Energy Distribution (SED) fitting. The photometric properties of these samples are then compared with those of individual LAEs bright enough to enable fitting of their SEDs, casting further light on the nature of these precursors to Milky-Way type galaxies.
