SIS profile does not produce radial critical curve
The SIS profile in lenstool only produce the external critical curve, ! This screenshot shows it on the left the magnification map at z_s=2 with the critical curve, on the right, it is the zonemult map created by lenstool which does not yield the correct results either. Screenshot_2022-11-05_at_15.03.00 and it should be something that looks this this http://gravitationallensing.pbworks.com/f/1218447069/SIS_soft.png
I attached here a tar file containing the lenstool files and map: in this directory launch SIS.par to reproduce what I show in the image.
