Distribution of the parameters from the 100,000 chain of MCMC results of the spectral fittings on the QPO phase 0.5-0.6 (for visualization purposes). The multi-parameter correlations indicate that only the continuum parameters, kT_e and τ from the thcomp, and kT and Norm from the comptt components exhibit strong correlations. In contrast, the strength of the absorption lines and edge show no significant correlation with other parameters.
