Notes. Size measurements from elliptical and circular aperture photometry. For three(two) simulated survey depths, we reported the Lyα emission sizes of the two stacks (LARS-LAE, LARSaverage) at z ~ 2(z ≃ 5.7). We also reported the continuum emission sizes of the two stacks in the lower part of the table at a 10σ detection limit of m_{rest − UV} = 30.0. F(Lyα) is given in erg s^-1 cm^-2.
