Comparison between the parallax-based distances of H II regions given by this work and the reference values. The red dots indicate the sources with estimated distances from the associated HMSFR masers primarily from Reid et al. (2019). The blue dots are the H II regions from Méndez-Delgado et al. (2022), whose distances are based on Gaia DR3. The grey line represents the equal line. Abbreviations for the references are: R19, Reid et al. (2019); M22, Méndez-Delgado et al. (2022).
