VizieR Online Data Catalog: NGC 6067 stars (Alonso-Santiago+, 2017)

We obtained high-resolution echelle spectra using FEROS (Fibre Extended Range Optical Spectrograph) mounted on the ESO/MPG 2.2-metre telescope at the La Silla Observatory, in Chile. FEROS covers the wavelength range from 3500 to 9200Å, providing a resolving power of R=48000.

The spectra were taken during four consecutive nights in 2011 May 10-13 under programme 087.D-0603(A). The exposure times ranged from 600 to 4800s to achieve a typical signal-to-noise ratio (SNR) of around S/N~=70-80 for blue stars in the classification region (4000-5000Å) and S/N~=90-100 for the cool stars (6000-7000Å). Later, in 2015 May, under programme 095.A-9020(A), we observed the star HD 145175 (star 229 in Table 1) with the same instrument. To complete our sample, we took from the ESO Archive Raw Data spectra of QZ Nor, observed originally in 2007 under programme 060.A-9120(B). In total, we have spectra for 48 stars.
