EW in mÅ vs. Reddening E(B – V) (mag.) for the NIR DIBs in the current sample. Blue points show all of the data, and orange points show only single component dominated sightlines. For the 1318 and 1527 nm DIBs for reddening exceeding 3.13 mag. the data are from the X-shooter Cepheid sample that suffer from stellar contamination of around 500 mÅ for un-reddened sightlines. The solid red line is the best fit y=mx+c and the dashed red curves show the upper and lower one sigma error bounds.
