Comparison of distance moduli for four systems (NGC 6121, NGC 5139, LMC, and SMC) with precise distances and uncertainties derived using different methods (other than RR Lyrae PMZ relations; Pietrzyński et al. 2019; Graczyk et al. 2020; Vasiliev & Baumgardt 2021). From the left, the plots show a comparison for globular clusters NGC 6121, NGC 5139, LMC, and SMC using distances and their uncertainties depicted with solid and dotted black lines in all three plots.
