Abstract:
    Observations of OB-stars, made in 1959 and 1960 at the Leiden Southern
    Station near Hartebeespoortdam, South Africa, with the VBLUW
    photometer attached to th e 90 cm light-collector, are given in this
    paper. They are compared with photome try obtained by Graham
    (1968BANS....2..397G), Walraven & Walraven (1977BAN....15...67W),
    Lub & Pel (1977A&A....54..137L) and van Genderen et al.
    (1984A&AS...58..537V). Formulae for the transformation of the present
    observations to those of Walraven & Walraven (1977BAN....15...67W)
    and Lub & Pel (1977A&A....54..137L) are given.
