Description:
The normal spectral energy distribution for spectral subtypes from O4
to O8 for luminosity classes V,IV and III are derived. Three
photometrically uniform catalogs served as the source of the
spectrophotometric data used. Synthetic color indices for all spectral
types are calculated using the energy distribution curves obtained.
