and D is the observed output flow rates for CH of the posterior was performed using MCMC, which proposes random jumps in parameter space and either proceeds with the jump or does not based on the probability of the jump destination. This algorithm was used to sample the HPD region of the posterior. MCMC sampling was performed using the Zeus package, which used a modification of the MCMC algorithm known as Ensemble Slice Sampling (ESS). This approach allowed MCMC chains to run in parallel, and communicate information about all active chains (i.e. the ensemble)
