  We created a large database of physical parameters and variability indicators
by fully reducing and analysing the large number of spectra taken to complement
the asteroseismic observations of the CoRoT satellite. 7103 spectra of 261
stars obtained with the ESO echelle spectrograph HARPS have been stored in the
VO-compliant database Spectroscopic Indicators in a SeisMic Archive (SISMA),
along with the CoRoT photometric data of the 72 CoRoT asteroseismic targets.
The remaining stars belong to the same variable classes of the CoRoT targets
and were observed to better characterize the properties of such classes.
Several useful variability indicators (mean line profiles; indices of
differential rotation, activity and emission lines) together with vsini and
radial velocity measurements have been extracted from the spectra. The
atmospheric parameters Teff, logg and [Fe/H] have been computed following a
homogeneous procedure. As a result, we fully characterize a sample of new and
known variable stars by computing several spectroscopic indicators, also
providing some cases of simultaneous photometry and spectroscopy.
