Notes. From left to right: (xL, yL) is the position of the source relative to the ALMA phase center given in the first two columns, with positive values corresponding to west; M is the mass of the lens galaxy; eL is the ellipticity; ϕL is the position of the major axis in degrees east of north; γ is the external tidal shear; ϕγ is the position angle of the shear, and μ is the derived lensing factor. Since the values were fixed during fitting of the source position, we do not report their respective errors. The magnification factor is taken to be the average across the line.
