Notes. First column: angular separation between the sources A and B. In the point-like source modeling (top), this is computed as the distance between the best-fit source positions optimized by GLEE, while in the extended modeling (bottom), it is computed as the distance between the brightest pixels associated with each source in the reconstructed SBs. The second, third and fourth columns show the half-light radii of the reconstructed sources estimated through their cumulative luminosity profiles. Fifth and sixth columns: local median magnification factors of the multiple images A1 and B1 and 1σ statistical uncertainties. They are measured as the median value of the median magnification maps within circles of radii r_e A1 and r_e B1, centered on A1 and B1. Last two columns: half-light radii of the sources A and B measured from the results r_e A1 = 0.23″ and r_e B1 = 0.17″ of the SB modeling of the multiple images A1 and B1, and demagnified with Eq. (11). The uncertainties are propagated from those on the magnification factors. The angular quantities are converted to physical ones for z = 1.880, unless otherwise specified.
