Stellar population–based distance to the Andromeda galaxy. Light-gray lines correspond to the 66 individual posteriors for the distance modulus, with each median indicated with a small vertical blue line. The black solid line shows the combined measurement of the distance modulus, with the 1σ uncertainty indicated with a blue vertical shaded area. For reference, the μ0 value and uncertainty of S. Li et al. (2021) are represented by the vertical orange line and shaded region, respectively.
