CCD photometry of galactic clusters containing cepheid variables - II. NGC 6067.
Abstract
A colour-magnitude diagram extending to V = 19 is given for 1019 stars in the open cluster NGC 6067. The true distance modulus is found to be 11.05±0.10 mag assuming E(B-V) = 0.35. A colour-magnitude diagram for an adjacent field shows that the Norma star cloud is at a similar distance to NGC 6067. The Cepheids CPD -53°7400A (p = 11.3 day) and HD 144972 (p = 3.8 day) have >MV< = -3.77±0.10 and >MV< = -3.27±0.10, respectively, if they are cluster members.
