Median H₀ inference for mock systems from Table 1 with χ² < 1.2 (see text for more information). The histogram for boxy galxies is displayed in blue, that for discy ones is in green, and the sum of both is in red. The histograms are representative of the retrieved H₀ values obtained in our systematic tests that encompass multipole amplitudes of plausible lenses. However, this does not represent an inferred H₀ distribution from a realistic population of lenses (see Fig. 9).
