Caption: Figure 5.

Corner plot showing the posterior distribution from our MCMC ellipse fit, including the RECON24 chord. At the top of each column are the marginal (one-dimensional) posterior distributions for each parameter; beneath those, joint (two-dimensional) posterior distributions are shown for each pair of parameters. Contours show the 0.5σ, 1σ, 1.5σ, and 2σ confidence regions. Black points correspond to samples from the MCMC chain.
