Descripción
We present a library of Utrecht echelle spectrograph (UES) observations
of a sample of F, G, K and M field dwarf stars covering the spectral
range from 4800 Angstroms to 10600 Angstroms with a resolution of
55000. These spectra include some of the spectral lines most widely used
as optical and near-infrared indicators of chromospheric activity such
as Hβ , Mg i b triplet, Na i D1, D2, He i
D3, Hα , and Ca ii IRT lines, as well as a large number
of photospheric lines which can also be affected by chromospheric
activity. The spectra have been compiled with the aim of providing a set
of standards observed at high-resolution to be used in the application
of the spectral subtraction technique to obtain the active-chromosphere
contribution to these lines in chromospherically active single and
binary stars. This library can also be used for spectral classification
purposes. A digital version with all the spectra is available via ftp
and the World Wide Web (WWW) in both ASCII and FITS formats. Based on
observations made with the William Herschel Telescope operated on the
island of La Palma by the Isaac Newton Group at the Spanish Observatorio
del Roque de Los Muchachos of the Instituto de Astrof\'{i
