Abstract

Spectrophotometric observations of 20 F, G, and K spectral class supergiants and bright giants have been obtained with the Harvard College Observatory scanner on the No. 10.9 m telescope at Kitt Peak National Observatory. The scans cover the wavelength range 3510-5520 A with a resolution of 30 A. The observed flux distributions have been corrected for instrumental effects, atmospheric extinction, and interstellar reddening. The resulting intrinsic flux distributions have been compared to theoretical flux distributions based on the model of Kurucz (1979) in order to estimate effective temperatures and surface gravities for eight of these stars.
