Notes. Comparing the cINN method with a Metropolis-Hastings MCMC scheme when applied to K2-111 b. ∆1σ and ∆2σ are the relative differences of the interval boundaries of the 1σ and 2σ intervals. The wrock and xFeO|mantle were calculated from the other layer mass fractions and other mantle oxide fractions.
