Posterior distributions for the MCMC runs with real data for five PRE bursts from 4U 1702−429. The panels and symbols are the same as in Figs. 3 and 5. The red solid line in the Dpanel shows the prior distribution () that we used. Both models are seen to produce posterior shapes that are similar to what we found in our synthetic data fits (Fig. 5). Both models also produce consistent estimates for the radius and distance.
