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.
