Example spectra showing the bluewards emission feature towards the 1318 nm DIB with heliocentric stellar velocities marked by vertical black lines. For HD 115363, HD 112272, HD 159455, and HD 160065, two spectra taken at different epochs are shown. HD 159455 has a shift in radial velocity between the two epochs. Kervella et al. (2019) use Gaia data to determine that this object has a tangential velocity anomaly of 2.4 km s⁻¹ and is hence likely a binary, although this should not affect the DIB absorption profile. The rest wavelength of the emission line is assumed to be 1317.30 nm.
