Notes. Source and galaxy positions (xs, ys) and (xg, yg) are relative to the position of the brightest lensed component (x1, y1) = 3600 · (α1 cos δ1, δ1). The combined chi-square,
from Eq. 3, has two degrees of freedom for all systems, except for 2MASSJ13102005-1714579 where one G-band flux is missing that leads to one degree of freedom. The root mean square error on the position and median positional uncertainty, both projected on the plane tangential to the celestial sphere, are respectively reported as rmspos and σpos, while the median S/N of the fluxes is reported as
. Although the galaxy position is left as a free parameter, eleven systems have at least one galaxy position that is reported in our catalogue. For systems with a single lensing galaxy, dg is the distance between the predicted and observed galaxy position. Other parameters are described in Sect. 6. Parameters are truncated to the last significant decimal according to the MCMC 0.16 and 0.84 uncertainty percentiles or are explicitly written if the uncertainty is larger than one. As an example, a tabulated value of θΕ = 1.328 means that its uncertainty stands between 0.001 (inclusive) and 0.01 (exclusive).
