Notes. All available photometric observations were fitted. ΩK denotes the Kopal surface potential here, and L the relative luminosity in the filter given by the subscript. U, B, and V denote Johnson filters, MO denotes the broad-band filter in the MOST satellite, and Hp denotes the broad-band filter of the satellite Hipparcos.
