Notes. The values in parentheses are the 1σ uncertainties in the preceding digits. If the distribution is not symmetric, we show the 68% uncertainty in the upper and lower half of the distribution (cf. Appendix A of Disberg & Nelemans 2023). (a)Non-Gaussian probability distributions (similar to e.g. Verbiest et al. 2012). (b)Weighted means of the DM-based distances from the Galactic free-electron density models of Yao et al. (2017) and Cordes & Lazio (2002), as computed by Ding et al. (2024). (c)Conservatively adopted uncertainties. (d)Determined using http://psrpop.phys.wvu.edu/LKbias/. (1) Kramer et al.
