Parameters of the four successful binary-lens finite-source parallax models, distinguished by the side on which the source passes relative to the lens near the peak (u0 < 0 or u0 > 0), and whether the binary lens is in a ‘close’ (d < 1) or ‘wide’ (d > 1) configuration. We adopted error bars arising from a scaling based on the off-peak data, and obtained a simple maximum-likelihood (ML) estimate on all data. The respective value of χ2 is reported for reference.
