CRIRES DIB spectra around 1318, 1527, and 1561–1568 nm. Main panels: Observations of all stars shifted in wavelength to 1318, 1527, and 1567 nm, respectively, and with absorption line trough normalised to 0.2. Top black line: Model of telluric absorption assuming PWV values of 1.3, 2.5, and 7.5 mm, respectively, with R = 50 000. Inset panels: Averaged profiles for the DIBs with the strongest lines and for 1318 nm DIBs excluding sightlines showing inverted P-Cygni type profiles.
