Central wavelengths and profile shapes of diffuse interstellar bands vs. physical parameters of intervening clouds

This paper tries to establish whether there are variations of the central wavelengths or the profile shapes of diffuse interstellar bands (DIBs) and whether these variations are caused by different physical parameters of translucent clouds. For this purpose we used spectra of two stars seen through two different single clouds: HD34078 (AE Aur) \& HD73882 acquired using two different instruments: the MIKE spectrograph, fed with the 6.5 m Magellan telescope at Las Campanas Observatory, and the UVES, fed with the 8 m Kueyen telescope at the Paranal observatory...
