Scientific paper

The catalogue of Keenan, Garrison, and Deutsch (1974) has been extended by the addition of 483 blue spectrograms of 72 Southern Hemisphere Mira-type variables. About 190 direct and image-tube plates at a dispersion of 120 Angstroms/mm were obtained in Chile between 1977 and 1982. Along with the spectral types and photographic magnitudes, emission ratios Hδ λ4101/Hγ λ4340/Hβ λ4861 and eye-estimated intensities of the absorption lines CaI λ4226, CrI λ4254, and SrII λ4077 have been tabulated. Spectral intensity tracings and magnitude-phase diagrams are displayed for a few of the best-studied Miras in the Southern Hemisphere program.
