Notes. The x and y coordinates are expressed in arcseconds with respect to the position of BCG-N, at RA = 3.586257, Dec = −30.400172. A single number is quoted for the fixed parameters. When a flat prior on a free parameter is considered, the boundaries of the prior separated by the ÷ symbol are reported. The number of galaxies optimized through the scaling relations (Ngal), and the reference magnitude (
) are also reported. We provide the input (top) and optimized (bottom) values of the output parameters of the reference lens model. For each free parameter, we quote the median, the 16th, and 84th percentiles of the posterior distribution.
