Mixture distribution of distance moduli in Table 5. Top panel: normal distributions with centers defined by μo and width (σ) corresponding to the error in μo. Bottom: sum of the normal distributions in the top panel. The dashed vertical line corresponds to the mean, also plotted as a point above the distribution. The widest error bars correspond to the 1σ, or 34.1%, of the total area starting from the center outward; the narrower error bars correspond to the error in the mean divided by the square root of the number of stars used in the fit, i.e., .
