De-reddened J and K_S magnitudes versus period (in units of days) for the seven known T2Cs in ω Cen. The dashed lines correspond to the empirical PL relations derived by Matsunaga et al. (2006), shifted to the distance modulus of the cluster used in that study, 13.62 mag, while the dotted lines are the same relations, but shifted to our derived distance modulus of 13.708 mag (see Sect. 4). V60 and V92, with roughly the same period and magnitude, are labeled accordingly.
