Fig. 7.
Posterior probability distributions of the vrnei model broadening width and velocity from the Fe K region fitting including line broadening. Notations are the same as in figure 6. The left-hand panel shows results with flat prior on the line width, while the right-hand panel shows results imposing a Gaussian prior with 1 σ width of 1000 km s−1. Both velocity distributions trace the cstat minimization well. The flat prior produces a broader posterior distribution. (Color online)
