Notes. These parameters correspond to the cored mass model. Coordinates are given in arcseconds with respect to α = 109.3982,δ = 37.745778. The ellipticity e is for the mass distribution. Error bars correspond to 1σ confidence level. Parameters in brackets are not optimized. For the scaling relations, the zero point is set to a magnitude equal to 20.66.
