In the column “Station”, the individual observing stations are identified by the running numbers from the Praha/Zagreb photometric archives:
1: Hvar 0.65 m reflector, EMI tubes; 2: Brno private observatory of P. Svoboda, Sonnar 0.034 m refractor with a CCD camera; 4: Ondřejov 0.65 m reflector, EMI tube; 12: La Silla 0.50 m Danish reflector: Part 1 are all-sky observations, the rest are differential observations secured during a long-term campaign. The original uvby observations were transformed to UBV; 20: Toronto 0.40 m reflector, EMI 6094 tube; 26: Haute Provence 0.60 m reflector, Lallemand tube; 30: San Pedro Mártir 0.84 m and 1.50 m reflectors (13C photometry), more recent UBV observations were secured with the 0.84 m reflector and Cuenta-pulsos photometer; 34: Lick 0.61 m Boller & Chivens telescope, refrigerated S20 tube; 37: Jungfraujoch Sphinx mountain station 0.40 m reflector, Geneva photometer; 44: MtPalomar 0.51 m reflector, EMI 6094 tube; 59: Cape Town 1.0 m reflector, UBV photometer; 61: HIPPARCOSHp photometry transformed into Johnson V; 66: Tübitak National Observatory 0.40 m reflector with SSP-5A photometer; 89: Çanakkale Mountain Station 0.40 m reflector, SSP-5 photometer; 90: Teramo 0.40 m refractor; 91: US Naval Observatory Ritchey-Chretien 1.0 m reflector, EMI 9524B tube; 92: Stefanion ESO Netherlands Van Straaten 0.40 m reflector, EMI 6256B tube; 93: ASAS3 automatic all-sky photometric survey.
