Introduction

This atlas is intended at providing a useful tool for the wavelength calibration of the VLT/ISAAC and NTT/SOFI spectra. Since OH lines are imprinted on all sky spectra (provided they are deep enough, which might not always be the case for standard stars), they provide an in-situ reference for wavelength calibrating the spectra.
