Abstract:
We present Echelle spectra of 91 late-type dwarfs, of spectral types
from F to M and of different levels of chromospheric activity,
obtained with the 2.15-m telescope of the CASLEO Observatory located
in the Argentinean Andes. Our observations range from 3890 to
6690Å, at a spectral resolution from 0.141 to 0.249Å per pixel
(R=λ/δλ∼26400). The observations were flux
calibrated with the aid of long slit spectra (R∼1050-2070), also
available.
