Illustration of H₀ estimates resulting from orthogonal paths. The two paths starting with “O” are proper orthogonal paths and can be taken as independent measurements of the Hubble constant. Their weighted mean (red) agrees well with our baseline result despite the latter including all cross-correlations. The shortcuts of the datasets are as defined in the text. The pie charts “fraction of data kept” represent the fraction of statistical power remaining in the path. It is computed as the fraction of the variance of H₀ for the given result (in this way multiple datasets with the same constraining power in H₀ will be assigned equal percentages). We show the percentages relative to the baseline result (V00).
