1 Otero, Sebastian Alberto J-K= 0.84. After comparison with light curves of the rest of the RV Tauri stars, this star is classified as a member of the class.
2 Otero, Sebastian Alberto It might be RVA with P= 147.8 d. But amplitude changes suggest SRD-type. Catalogued as PMS star everywhere but light curve suggests otherwise.
