  We obtained spectra of 26 bright stars in the southern sky, including Sirius,
Canopus, Betelgeuse, Rigel, Bellatrix, and Procyon, using the 1.5-m telescope
at Cerro Tololo Inter-American Observatory and its grating spectrograph RCSPEC.
A 7.5 magnitude neutral density filter was used to keep from saturating the
CCD. Our spectra are tied to a Kurucz model of Sirius with T = 9850 K, log g =
4.30, and [Fe/H] =+0.4. Since Sirius is much less problematic than using Vega
as a fundamental calibrator, the synthetic photometry of our stars constitutes
a Sirius-based system that could be used as a new anchor for stellar and
extragalactic photometric measurements.
