Notes. The photometric data is described in Sect. 2. K and (J − K) are given for the corresponding pulsation phase φ. Periods are taken from Lebzelter & Wood (2005; uncertain values are marked with a colon). The photometric variations ΔV were adopted from Lebzelter et al. (2005), while the estimates for Teff and log g are described in Sect. 3.2.
