Oguri+11 (https://arxiv.org/pdf/1109.2594.pdf) used GLAFIC to generate lens model for cheshire cat. That model used 9 lensed image, now known as system A,B,C in Bayliss paper. The redshift of the lensed images used to generate Oguri's model is z=2.198, same redshift as system A but differ from B & C.


In my model generated using WSLAP+, I used 19 lensed images from 4 systems.

Here I compare the critical curve z=2.198 ( System A, right side of face) in 2 models as requested by Tom.



Oguri's GALFIC critical curve z=2.198. green squares are lensed images

WSLAP+ model z=2.198

The general size and shape of critical curve is similar in two models, there's a small difference occurs near the smile (system C) since I used z=2.783 (Bayliss et al. 2011) instead of Oguri's z=2.198.

It is also noticeable that Oguri's model extended to the left compare to WSLAP+. I think it is also due to difference in redshift used ( I used z=0.9657, while Oguri used z=2.198)
