Description:
Energy distributions for 33 galactic (super)giants situated mostly in
the southern Milky Way in the range from 4800 to 7700 Angstroems with
an effective resolution of 10 Angstroems are presented here. The
observations and reductions are described in the paper. The errors of
the absolute and relative flux calibration are 0.028 and 0.021 mag,
respectively. The S/N ratio is at least 80 for each star. Cross
references, MK classifications and spectral indices one may find in
the paper. Further informations are available at M.O.Oestreicher
(mio@astro.ruhr-uni-bochum.de).
The data are given in three files:
1) stars.dat
A list of the programme stars listing the HD/HDE numbers, MK types
and positions related to J2000
2) absolute.dat
A list of absolute fluxes for each star observed under photometric
conditions (18 stars). The fluxes are given in magnitudes according
to the system of Hayes & Latham (1975). A monochromatic magnitude
of 0.00 corresponds to a flux of 3.5x10^-20^ erg.cm-2.s-1.Hz-1,
(3.5x10^-23^ W/m2/Hz), i.e. the fluxes are related to
FREQUENCY INTERVALS.
3) relative.dat
A list of relative fluxes for each star observed in nights of low
quality (15 stars). The fluxes are normalized to 1 at 5555 Angstr.
and are related to WAVELENGTH INTERVALS.
