Descripción
In this contribution we summarise our science preparation activities to
complete the CARMENES input catalogue of M dwarfs using low-resolution
spectroscopy to derive spectral indices sensible to spectral type,
gravity and metallicity as well as the level of chromospheric activity.
We provide here all this information for 181 stars in addition to the
727 stars already published in Alonso-Floriano et al. (2015). We have
developed a calibration of the M-dwarfs metallicity (Alonso-Floriano et
al. 2016) using physical binaries composed of an F-, G- or K-dwarf
primary and an M-dwarf secondary that allows us to provide the
metallicity for all these M dwarfs.
