Abstract:
We present 187 high-resolution spectra for 62 different M1 dwarfs from
observations obtained with the FIbre-fed Echelle Spectrograph (FIES)
on the Nordic Optical Telescope (NOT) and from observations with the
Fibre-fed Extended Range Echelle Spectrograph (FEROS) from the
European Southern Observatory (ESO) data base. We also compiled other
measurements available in the literature.
Description:
The high-resolution FIbre-fed Echelle Spectrograph (FIES) is a
cross-dispersed high-resolution echelle spectrograph at the Nordic
Optical Telescope (NOT). The entire spectral range of 370-730nm
is covered without gaps in a single, fixed setting.
The European Southern Observatory (ESO) Fibre-fed Extended Range
Echelle Spectrograph (FEROS) is a bench-mounted, thermally controlled,
prism-cross-dispersed echelle spectrograph. It is designed to be a
high-resolution (R=48000), high-efficiency (20 per cent),
versatile spectrograph providing in a single spectrogram almost
complete spectral coverage from 350 to 920nm.
