Description:
New spectrophotometric data for 3 galactic and 23 LMC F to G
supergiants are presented. The wavelength range of the spectra is 3400
to 6400Å, the resolution about 10Å. The mean transformational
error of the fluxes is 0.03mag. The S/N ratio is about 100 and 30 for
galactic and LMC stars, respectively. Details about the reduction one
may found in Oestreicher & Schmidt-Kaler (1998MNRAS.299..625O 1998MNRAS.299..625O) and
Malyuto et al. (1997MNRAS.286..500M 1997MNRAS.286..500M). The fluxes are given in
magnitudes according to the system of Hayes & Latham
(1975ApJ...197..593H 1975ApJ...197..593H). For each star an ASCII file is given with the
name of the first identifier. In the first column the wavelength, in
the second column the flux is given.
