Same as Fig. 4, but with an exposure time of 3000 s instead of 5400 s and the unlensed quasar and extended source fainter by 1.75 mag. Those results are also displayed in green in Table 1. We note that the mask, which is defined by a threshold of twice the background noise, may sometimes have holes inside the Einstein ring due to the lack of lensed signal at those locations.
