VI/50       Energy Dist Stellar Spectra. V. Normal Stars (Sviderskiene 1988)
================================================================================
Energy Distribution in the Stellar Spectra of Different Spectral Types and
Luminosities. V. Normal Stars
    Sviderskiene Z.
    <Vilniaus Astron. Obs. Biul. No. 80 (1988)>
================================================================================
ADC_Keywords: Energy distributions ; Spectrophotometry

Description:
   Mean energy distributions are given for 98 normal stars in the spectral
   range from O to M and luminosity classes I, II, III, IV, and V. The
   points cover the wavelength range from 1200A to 10500A and a include a
   point at 12500A.

Introduction:
   The energy distributions were based on photometric and
   spectrophotometric data from many authors. All stars are dereddened. The
   zero point for each wavelength is based on a Vega model atmosphere by
   Mihalas (1966) with theta effective = 0.525 and log G = 4. It has been
   extended into the ultraviolet using the OAO 2 results. This energy
   distribution is given in the first file and can be used to change to
   another system if desired. The ultraviolet portions are based on the IUE
   calibrations. The energy distributions are given in intensities per unit
   wavelength interval normalized to 100 at 5500A. Each value given in the
   catalog is the intensity in the interval delta lambda = 50A centered on
   the given wavelength.
