Description:
This catalogue contains R-band spectra for 13 early-type supergiants.
Spectral types range from B0 to A6, all with luminosity classes Ia or
Iab. Eight of the stars are classified as having emission. The
wavelength range is 5846 to 7030Å at a spectral resolution of
1.2Å, and a signal-to-noise ratio of 400 or above.
Identification of spectral lines in supergiant spectra can be found in
Chentsov et al. (2003A&A...397.1035C 2003A&A...397.1035C). The reader should be aware of
the blends of atmospheric telluric lines that contaminate the spectra
in the ranges 5870-5995Å, 6270-6315Å, 6470-6500Å, and
6850Å onwards.
