Comparison of cINN posterior modes and PHANGS MLEs for all (filtered) NGC 1433 clusters. Top panels: cINN MAP modes as determined by the mean-shift estimator. Error bars show the 16%- and 84%-quantiles of the marginalized posteriors. The yellow markers indicate the positions of the four example clusters. Bottom panels: comparison with the posterior modes that were closest to the PHANGS MLE (for every posterior, a maximum of three modes were determined). For better visibility, we omitted the error bars. The blue dots mark clusters that have relative flux uncertainties larger than 40% in at least one UV band, as discussed in Sect. 3.2.4. The arrow shows the position of the largest outlier. Comparisons for all galaxies are provided in Appendix B.
