Scientific paper

New diagrams are presented for the assimilation of MK spectral types with uvby-beta photometry. Recently published mean uvby colors and beta indices for a wide selection of spectral types (Moon, 1985; Kilkenny and Whittet, 1985) are used for the revised diagram uvby values and the construction of a (c1), beta diagram for stars earlier than about AO. The Crawford and Mandwewala (1976) theoretical reddening ratios of E(ml)/E(b-y) equal to -0.33 and E(cl)E/(b-y) equal to 0.19 are used, and the supergiants are not displaced from the Main-Sequence band. The data provide estimations of the spectral types of normal stars and chemically peculiar stars, and show the separation of the luminosity classes.
