m_F275W versus m_F275W − m_F438W CMD of the central field of ω Cen, based on the catalogue from Bellini et al. (2014). These data correspond to the HST observations that enabled the discovery by Bellini et al. (2013) of the split in the upper part of the WD CS, down to an effective temperature of approximately T_eff ∼ 15 500 K.
