Distribution of the difference (Δμ) between our PNLF values of the distance modulus and those derived using SBF by Blakeslee et al. (2009). The Δμ distribution has a measured scatter of 0.21 mag around a median of 0.003 mag, as also shown by the reference Gaussian distribution with such median and standard deviation values. We adopt 0.12 mag bins to match Fig. 6 from Ciardullo (2012).
