VizieR Online Data Catalog: Constraining cosmic scatter (Reggiani+, 2017)

The observational data were obtained with the UVES spectrograph at the 8.2m VLT telescope, during 2015A (project 095.D-0504(A)). All the spectra were taken with the same instrumental configuration, which guarantees similar spectra quality and improves the precision in a line-by-line differential analysis. The blue side of the spectra has an effective range from 330nm to 450nm, and the red side of the spectra has a range of 480nm-680nm. We used a 0.8" slit on both arms of the spectrograph, with a final resolution of R=50000 per pixel in both the blue arm and red arms. The average S/N of the sample is: S/N=130 at 4000Å and S/N=250 at 6000Å. All equivalent widths were measured manually using the splot task in IRAF.
