Notes. The angular x and y positions and the scalar magnification μ for each lensed image. The images are numbered in the clockwise direction starting with the brightest image, as in Fig. 6, frame A. The angular coordinates are given relative to the centre of the lens at RA $^{° h' m ″ s} 17 ° 51' 7 \overset{″}{.} 46$ $^{\circ\mathrm{h}{{\prime}}\mathrm{m}{{{\prime\prime}}}\mathrm{s}}{17\circ51{{\prime}}7{{\overset{\prime\prime}{.}}}46}$ , Dec $+ 50 \overset{″}{.} 78$ $+50{{\overset{\prime\prime}{.}}}78$ . Magnification values are given to a fiducial precision of one decimal place, discussed in Sect. 4.3.
