Parameter distributions from our lens modeling results using the SIE + γ_ext model. Top row: gives the Einstein radii and external shear values of the mass model. Middle and bottom rows: effective radius and Sersic index, for the lens and source light, respectively. The models with an acceptable reduced χ² (≤3.0) are shown in green and those with a reduced χ² > 3.0 are shown in red (see text). After a manual fix of the masking procedure, the bad fits improved to χ² < 3.0.
