Description:
Optical spectra for candidate brown dwarfs from the DENIS Mini-survey
are provided. These are the spectra used to in Figure 1 of the paper.
Introduction:
These data were acquired with the Anglo-Australian Telescope and
the RGO Spectrograph. The FWHM resolution is 0.7nm at a dispersion
of 0.34nm. Wavelength coverage extends from 648nm to 989nm.
Atmospheric absorption is not corrected, making the data longward
of 920nm suspect.
