Images of the lens systems, part of the collected 2D spectra, and the corresponding 1D spatial profiles. The 1D spatial profiles have been generated by collapsing the data in the 2D spectra along the spectral axis. The slit position (green) for each lens system is also shown. For the lens system, J0147+4630, J0659+1629, J0818−2613, J1433+6007, and J1817+2729, we have used archival HST images (PI: T. Treu) and for B04453+123, B0631+519 and J0924+0219, we have used ground based AO images (PI: C. D. Fassnacht).
