Calibrating RAVE fluxes with STELLA
Within the Radial Velocity Experiment (RAVE) survey in total 574,630
low-resolution spectra of 483,330 stars covering the Ca II IRT has been
obtained. We have selected the late-type dwarfs from the database,
converted the measured 1-Ang core equivalent widths into the fluxes, and
obtained follow up high-resolution spectra of selected targets as well
as spectra of MK standard stars using SES (STELLA échelle spectrograph)
at STELLA (STELLar Activity) telescope. With a single exposure, we cover
all wavelengths from Ca H&K to IRT and can therefore relate IRT fluxes
with those of other activity indicators, such as Halpha. Furthermore, we
can place these fluxes in relation to observable astrophysical
parameters, such as global metallicity and temperature.
