Mean SED properties derived for individual LAEs in several publications at different redshifts; at z ~ 3/3.7 with a light blue/green point from Ono et al. (2010a) and Finkelstein et al. (2009a). Red points are at z ~ 5.7 from Lai et al. (2007), Pirzkal et al. (2007) and at z ~ 4.9 from Yuma et al. (2010) and the dark blue point is the mean of a sample of z ~ 0.3 LAEs from Finkelstein et al. (2009b), with confirmed AGN excluded (Finkelstein et al. 2009c). The black circles marks the mean in our sample of 40 best fit candidates; the filled circle is for the sub-sample with two populations and the open circle is for the single (young) population galaxies.
