Extended Data Fig. 5: Posterior probability densities of the best-fit parameters when fitting individual PIONIER epochs.
From: Microlensing mass measurement from images of rotating gravitational arcs
The figure displays the posterior distributions of model parameters α1 (direction of the line joining the center of the images with respect to the East-West axis), θE (angular Einstein ring radius, in mas) and η1 = ρ/u1 (ratio between the angular radius of the source and its distance from the microlens). Panel a corresponds to 12 July, panel b to 19 July and panel c to 21 July. The median values of the best-fit parameters are shown on top of the individual histograms with their 68 %-confidence intervals.
