Left: rP20^ell (kpc) measured in the original LARS images as a function of the value from the high-z simulated ones. The 1:1 relation is shown as a dashed line. Right: Δsize = as a function of rP20^ell measured in the original LARS images. The black dashed line indicates Δ = 0; the dashed blue, green, and red lines the median Δ values for Lyα, rest-frame UV, and optical. Open circles indicate LARS-LAEs; blue, green, and red dots correspond to the measurements in Lyα, rest-frame UV, and optical images.
