The values of astrophysical parameters for 9 604 stars of spectral types O through F have been estimated and are available on magnetic tape or microfiche. The 19 888 stars in the Hauck-Mermilliod catalogue (1980) of homogeneous four-color data were separated into B, A intermediate, A, and F groups by means of Strömgren's bracket quantities. The indices were dereddened according to the formula appropriate for each group and the resulting intrinsic colors matched to colors predicted from the atmospheric models of Kurucz to obtain estimates of the astrophysical parameters θe and log g. The values of Mv and [Fe/H] were calculated from empirical formulae.
