All possibly linked system

All regions

1. All C and I1 ; Spec-z

2. S1, T1, X1

3. A1,A2,A3 ; Spec-z

4. B1, B2, B5 (B3?) ; Spec-z

5. J1, J2

6. G1, H1, K2

7.K3, V1, D1 (potentially linked to B) (D has spec-z)

System C and I1 , has spec-z

I1 at top right

C3 is resolved into 5 lensed images , which, in the smile region, radially outward could be represented by C3 from left to right. i.e. I1 is the C3 left component. C2.1,C7 and or C4 could be the centre three, C5 and C6 in the right

I would match SED in the following:

C5 and C6 pink and brown , which has very similar SED

(C1.1 and C2.1 are the pair which we originally identified. but the SED peaks at different filters. I have reservation on whether they are indeed the same pair.)

Based on SED, I will pair up C2.1.2 , C2.2 and C7

C1.2.2 and C2.1.1

C1.1.2 , C1.2 and C4

However , I am unable to pair up C1.1.1 due to a peak at 390nm

Anyway, base on this pairing, I would suggest the critical curve cutting twice like this, (of course there could be ambiguity here)

Repeat pairing here: C112, C1.2, C4 . & C1.2.2, C2.1.1 & C2.1.2, C2.2, C7

Also note that I1 and G1 are not related

System S&T&X similar SED, not spec-z information

System A, with high-confidence spec-z

System B, SED all agrees except B4( next to the nose) which could cause by contribution from BCG in longer wavelengths

system J, no spec-z

System G&H&K no spec-z

System K3 V1 D1. D1 has spec-z of z=0.802, potentially linked to system B, so I also plotted system B SED here.
