Short summary
Experience of differential atmospheric absorption spectroscopy (DOAS) shows that a spectral shift between measurement and reference spectrum is frequently required in order to achieve optimal fit results. The shift is often attributed to temporal instabilities of the instrument but implicitly solved the problem of the tilt effect discussed in this paper. The tilt effect results from the finite resolution of the measurements and amounts to 2 pm for the example data set.
