Three composite mass profiles drawn from our sample, with the Einstein radius (green, dotted) and NFW scale radius (blue, dotted) indicated. The implementation of these composite profiles is shown for NFWp (red dashed) and NFWm (gray solid) DM profiles. Top row shows isodensity contours; second row shows ellipticity as a function of semimajor axis; third row shows b₄ as a function of semimajor axis. The bottom panels show the radial profile over a log scale, defined as the value of κ in a circular annulus at a given radius, rather than with respect to semimajor axis, expressed relative to the NFWm radial profile. The composite profiles are plotted as well as both components individually. Units of distance are now in arcseconds.
