Each directory contains separate CRIRES spectra of individual settings in ascii format.
Files with the suffix "_div.asc" were derived by dividing the spectrum by a synthetic stellar spectrum.
Wavelengths from pipeine reduction are not always accurate and show deviations up to one Angstrom.
All wavelengths are in vacuum and barycentric restframe.

Spectra which are not corrected using molecfit have mostly two wavelengths: "Wavelength_model" and "Wavelength".
"Wavelength_model" is the wavelength calibrated with the help of a physical model of the CRIRES spectrograph.
The "Wavelength" was calibrated only with a calibration lamp.
It depends on the individual spectrum, which wavelength is preferable.

Spectra corrected with molecfit have a comment in the header: "Wavelength calibrated with telluric lines."
This calibration is mostly very accurate.
