Catalogue of Mean UBV Data on Stars
註釋The fundamental paper by Johnson and Morgan describ Cape BV (Arp 1958) system, Eggen's UBVE (Eggen ing the standard stars, the first cluster observations, and & Sandage 1960), the U BV RI in the Johnson (Men the properties of the U BV system was published in 1953 doza 1963), Kron (Kron & Smith 1951), Cousins (1980), Kunkel & Rydgren (1979), Moffet & Barnes (1979), and (Johnson & Morgan 1953). We celebrated in 1993 the th 40 anniversary of this photometric system, which be Neckel and Chini (1980) systems. The references allow came used all around the world. Although some justified one to distinguish the original system in which the U BV criticisms were raised against the definition of the U filter data were obtained. The relation is given in Table I. or the original reduction procedure of the U - B index, As discussed in Mermilliod (1987a), numerous checks the U BV photometric system contains two of the most have been performed to improve the reliability of the important parameters, namely the apparent V magni data. The preparation of the Hipparcos Input Catalogue tude and the B - V colour index. They are very much required the confrontation of photometric data, not only used, but no recent catalogue of mean values has been within the U BV system, but also with other systems prepared for several years, although the number of pub (Geneva 7-colours, uvby, Walraven).
