Fig. A.4


Fit residuals from the epochs (E1 and E2) used to estimate the impact on BW distances for all four Cepheids, cf. Table 1. For Car and RS Pup, both the cycle-to-cycle and longer timescales are shown. The earlier epoch is represented by green x markers, the later epoch by black open circles. For each epoch, the rms around the fit and median measurement uncertainty, σ, are printed in the corresponding panel, indicating excellent fits.
