Delens-relens and geo-z of lensed images without spec-z

System J , the reddish arc next to system A

The delens-relens result here shown are produced with redshift of z=2.2, which is the redshift for system A.

Delens relens of J1 : the upper arc

Delens relens of J3 : the lower arc

Geo-z is 2.26, with dispersion of 0.018 arcsec.

SED shows that all three components belong to the same system

System G:

Delens-relens result are produced with geo-z = 2.02

Delens-relens of G1 :

G2

G3:

SED of all G systems:

G2_prime - deducted BCG component

Geo-z : 2.02 with 0.4arcsec source dispersion.
