The normal energy distributions in stellar spectra: Giants and supergiants

We have derived the normal spectral energy distributions for those early-ty pe subgiants, giants, and supergiants that were not investigated in our ear lier studies, which were in most cases also not included in the studies of Sviderskiene. Color indices computed using our normal energy distributions are in good agreement with normal colors derived from observations in the V ilnius photometric system. The reliability of our distribution curves is al so demonstrated by comparisons of observed and computed (W-B)-(B-V) two-col or diagrams in the WBVR system. Normal color indices for the photometric WB VR system are derived. (C) 2000 MAIK "Nauka/Interperiodica".
