Abstract:
Towards constructing a system of high-dispersion spectroscopic
standard stars with well-established abundances, so that adequate
reference stars of similar properties may be found for precise
differential abundance studies of any near-solar type stars, we have
collected high-resolution (R∼70000) echelle spectra for 160 F-K dwarfs
and subgiants of the solar neighborhood in three wavelength regions
(5000-6200Å, 5800-7000Å, and 7600-8800Å) at Okayama
Astrophysical Observatory. This spectra database is open to the
public.
Description:
Observations were carried out over the period from 2000 October
through 2003 May using the HIgh-Dispersion Echelle Spectrograph
(HIDES) at the coude focus of the 188cm reflector at Okayama
Astrophysical Observatory. Equipped with a 4Kx2K CCD detector at the
camera focus, the HIDES spectrograph enabled us to obtain an
echellogram covering a wavelength range of ∼1200Å with a typical
resolving power of R∼70000 (case for the normal slit width of 200µm
in the mode of red cross-disperser.

Note (1): The data of VMAG were derived from the plx and Vmag values taken
from the Hipparcos Catalogue (ESA, 1997, cat. I/239), except for
HD 137108 for which we consulted the plx value of Jenkins (1952, Cat.
I/81) and the SIMBAD Vmag data. All other data were adopted from the
SIMBAD database.

Note (1): Most of the spectra are observed in the standard wavelength
regions (covering ∼1200Å) centered at 5610Å (G), 6440Å (R),
and 8210Å (I). However, spectra obtained at the early stage of
this project were observed with different settings, and thus their
wavelength coverings are accordingly somewhat different. The number
after [G, R, I] indicates the value of the shift-relative to the
standard wavelength range. (For example, "R+120" means that the
mid-wavelength of the R-region is 6560Å instead of the standard
6440Å). The term "s100(g)" denotes that a slitwidth of 100µm
was used for the G-region observation, instead of the standard width
of 200µm.
