Limits of 1, 2, and 3σ for microlensing parallax components for the u₀ < 0 solution derived using different methods and data sets. Here we present ground-based+Gaia contour (green, large ellipse), Spitzer-“only” solution with free blending (blue elongated ellipse), and Spitzer-“only” solution with a constraint on the blend flux (small red ellipse in the middle). The black dashed ellipse shows the microlensing parallax components distribution obtained with a joint fit to ground-based, Gaia, and Spitzer data. It is almost identical to the solution obtained using the Spitzer-“only” constrained method. We also include 1, 2, and 3σ PIONIER constraints derived in C21 (grey bands).
