Histograms of accepted steps from MCMC sampling of experimental data in Fig 2B.

One-dimensional histograms of (A) γ and κ values with best-fit parameters (blue line) and 15.8th and 84.2nd percentiles (black dotted lines). The histograms follow a Gaussian distribution (black solid line) as assumed in the Hessian method. Two-dimensional histogram of (B) γ and κ values with best-fit parameters (blue lines). The contour (black) lines are the one, two, and three standard deviations. Points outside of three standard deviations are plotted individually.
