The spectra for the article: Chemical abundances of seven stars in the GD-1 stream

This dataset presents normalized one-dimensional spectra for seven member stars of the GD-1 stream, obtained using the Subaru Telescope's High Dispersion Spectrograph (HDS). The observations were conducted in March 2020 with the standard StdYd setup, delivering a spectral resolution of R≈36,000 across the wavelength range of 4000-6800 Å. The data reduction process was performed using the IRAF echelle package, following standard procedures: bias correction, scattered light subtraction, flat-fielding, and spectral extraction. Wavelength calibration was achieved using Th-Ar arc lines, and cosmic rays were removed following the method described in Aoki et al. (2005). The continuum was normalized by fitting low-order polynomials to carefully selected spectral windows.
