Notes. The A image is at the origin of coordinates (0, 0), and the positive directions of x and y are defined by west and north, respectively. (xB, yB) is the position of B and B/A is the image flux ratio. The last six parameters in Col. 1 correspond to the main lensing galaxy G: position (xG, yG), effective radius reff, concentration index n, ellipticity e, and position angle of the major axis θe (it is measured east of north). Column 2 gives the previous results by Inada et al. (2009), and the new parameter values are listed in Cols. 3−5.
