Abstract:
A large number of stars from photometrically homogeneous catalogs are
used to derive the normal energy distribution for giants of 15
spectral subclasses. To judge the reliability of the results obtained,
the mean (B-V)S color indices calculated for a sample of stars with
spectrophotometry are compared with the mean (B-V) for a complete
sample of stars of a given subclass from the Bright Star (V/50)
catalog.
