Table A.1: X and Y coordinates in arcsec for the 26 knots used in the modeling. Coordinates are referred to the cD center and are oriented as in Fig. 1. The first part consists of the tangential arc system. The first 13 are 5 times imaged and the next 6 are triply imaged. The (*) denotes the brightest spot in the arcs and is the only point which are seriously observed in the fifth image. On the other side, the radial arc consists on triply images dots only. A1in (resp. A1out) is the inner (resp. outer) part of the composite radial arc. Both are imaged into the Eastern extremity of A5. In this later case, associations of mid points (x,y)=(8.3, -22.4) are somewhat ambiguous and are given less weight for the modeling. The tangential and radial systems were used simultaneously since we established they are at the same redshift . The system {A'1-A6} is found at a slightly lower photometric redshift and can only be compared with the modeling at a later stage.
