Cheshire cat v2 run13e

In this model, I increased number of cluster members included, total 29 cluster members are included. I checked all of them with red-sequence method and 9 of them has spec-z.

Those with spec-z are marked purely numerical.

Outlier : the cluster member Color_3 next to lensed image - Nose ,Instead of fixing it according to LTM, I allow glafic to calculate for me.

Mass distribution :

Radial Profile:

Delens-relens A1:

all good agreement , predict dim image near left eye that doesn't observe.

A3

Critical Curve

Geo-z

spec-z 2.198, geo-z 2.21, dispersion : 0.15arcsec

_____________________________________________________________________________

System B:

Delens-relens B1:

Major Improvement in position : B2 extend northbound by 0.3 arcsec, smaller than previous model , but predict a dim unobserved counterimage near right eye.

B2:

Critical Curve:

Spec-z: 0.9657 , geo-z 0.83, dispersion 0.28 arcsec

J1:

Good positional agreement, predict dim image near M1

J2:

Critical Curve

Geo-z :2.19, glafic-derived 2.1823 , dispersion : 0.1 arcsec

_____________________________________________________________________________

AB: Predict dim image near right eye

Nose :

Good agreement in general, extra stuff on the right side should be due to delens-relens of cluster member top left of the nose, hence yellowish.
