NIR DIBs at 11 797 Å (left panel), 13 175 Å (middle panel; Joblin et al. 1990), and 15 268 Å (right panel; Geballe et al. 2011) are shown for the X-Shooter sample of sightlines. The spectra have been corrected for the presence of telluric lines and subsequently for the radial velocity of the ISM. The dashed lines indicate the rest wavelength for the respective DIBs. Solid green curves show the Gaussian model fits and the blue solid curve displays the telluric model spectrum.
