Posterior distributions for the free chemistry retrieval which included an offset in the HST WFC3 G141 data. The retrieval converges to a solution which has a slight offset, but the “no offset” solution is well within the 1σ uncertainties. Furthermore, the Bayesian evidence for this retrieval is significantly less than that of the same retrieval minus an offset parameter. The difference in the Bayesian evidence suggests an offset between the data sets is rejected at the 3.7σ level.
