In this work we present spectroscopic observations
centered in the spectral lines most widely used as
optical indicators of chromospheric activity
(,
, Ca II H & K,
and He I
)
in a sample of F, G, K and M chromospherically inactive stars.
The spectra have been obtained with the aim of providing a library of
high and mid-resolution spectra 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.
