Abstract:
Over the last decades, libraries of stellar spectra have been used for
a large variety of science cases as well as of sources of reference
spectra for a given object or a given spectral type. Despite the
existence of large libraries, and the increasing number of projects of
large scale spectral surveys, there is to this date only one very high
resolution spectral library, offering spectra from a few hundred
objects from the Southern hemisphere (UVES-POP). We aim at extending
the sample, offering a finer coverage of effective temperatures and
surface gravity, with a uniform collection of spectra obtained in the
Northern hemisphere.
Between 2010 and 2020, we have acquired several thousand echelle
spectra of bright stars with the MERCATOR-Hermes spectrograph
located in the Roque de Los Muchachos Observatory in La Palma, whose
pipeline offers high quality data reduction products. We have also
developed methods to correct for the instrumental response, in order
to approach the true shape of the spectral continuum. Additionally, we
devised a normalisation process in order to provide a homogeneous
normalisation of the full spectral range for most of the objects.
We present a new spectral library, consisting in 3256 spectra covering
2043 stars. It combines high signal-to-noise and high spectral
resolution over the entire range of effective temperatures and
luminosity classes. The spectra are presented in four versions: raw,
two 'Spectral Energy Distribution' (SED) versions, both corrected
from the instrumental response, with and without correction for the
molecular absorption of the Earth's atmosphere, and a normalised
version of the telluric corrected spectrum.

Metaspec.dat provides the main parameters describing the spectra and
the corresponding targets.
meta-cal.dat provides the links between the spectral library and the
calibration observations used for the instrument response correction.
The information provided in this file was also reflected in the
primary header of the spectra.
metagaia.dat contains the result of the cross-matching of our dataset
with the table gaia_source of Gaia-DR3 using a cone search of 3 arcsec
for 1592 Melchiors stars.
