This standardized document follows the rules of the Standard Description for Astronomical Catalogues. For those having to work on this catalogue using FORTRAN programs, this ReadMe file can be transformed into a f77-compliant program which reads the files making up this catalogue, in two versions: either a f77 program loading whole files into arrays, or a f77-program reading each data file line by line.

Abstract:
    The authors present digital spectra of O to M stars, luminosity
    classes V, III, and Ib in the wavelength range 5750-8950Å, at
    15.5Å resolution. The stars follow well defined morphological
    sequences in both temperature and luminosity. This wavelength region
    and resolution, combined with the high sensitivity of silicon-based
    detectors, are very useful for spectral classification. Details of
    the observations, identifications of the main spectral features, and
    spectral lines most sensitive to temperature and luminosity are given
    in the paper.
