Notes. The aperture size of the two filters was $r = 0 \overset{″}{.} 28$ $r = 0{{\overset{\prime\prime}{.}}}28$ . The S/N of the two sources was 2.3 and 2.2.f_esc was calculated by the intrinsic model, and f_esc, SED was derived from the SED fitting. M₁₅₀₀, β, and M_* were corrected for the lensing effect.
