摘要:An incorrect zero point for the empirical period-luminosity-
metallicity (PL-Z) relations for RR Lyrae (RRL) stars in ω Cen-
tauri (NGC5139) was inadvertently reported in Table 2 and
Eqs. (4) and (5) of our original paper. The corrected table and
equations are given below. The actual analysis that is described
inthepaperwasbasedonthecorrectzeropoints,andsoallofthe
results reported in our original publication remain unchanged.
