ALMA mm-continuum positions, peak surface brightness and flux-densities for the lensed quasar images (A, B, C and D) and for the lensing galaxy (G), together with their relative positions in the optical (Claeskens et al. 2006; Suyu et al. 2013).

Notes. The absolute positions are quoted relative to the phase-referenced position of image A (RA = 11:31:51.582, Dec = −12:31:58.88). The uncertainty in the surface brightness and flux-density is assumed to be 10%.
