Cumulative projected total mass profiles for the PIEMD+rc (blue) and SPEMD (red) models with ±1σ uncertainties (shaded areas), obtained by modeling the multiple images of A, B, and C as point-like objects. The cumulative projected stellar mass profile from Fig. 4 is shown in dashed black. The vertical lines close to the x-axis locate the distances from the lens galaxy center of the different multiple images, color-coded following Figs. 1 and 6. The black line shows the effective radius of the main lens galaxy.
