Markov Chain Monte Carlo plots for parameter variations of XRT2 and XRT15 are presented. Goodman–Weare (EMCEE; D. Foreman-Mackey et al. 2013) is opted for 32 walkers and a chain length of 1 million iterations, where the transient phase is removed by burning the chain up to 9984 iterations. The spin parameter was kept frozen at a = 0.60 to perform the MCMCs.
