Notes. V magnitudes and periods are from OGLE IV, except for HV 12202, for which they have been found in Molinaro et al. (2012) and Musella et al. (2016). Column 7 refers to the Teff derived from the line depth ratio method (LDR, Kovtyukh & Gorlova 2000) while Col. 8 is the Teff derived from the excitation equilibrium. The last column lists the S/N around 5228 and 5928 Å, respectively.
