Atmospheric models (transit depth as function of wavelength) for OH (brown), Fe (green), V (magenta), CO (red), H₂O (blue), and TiO (orange) generated with the SCARLET code. The shaded regions highlight the spectral coverage of each instrument. The range of the wavelength of HARPS is in yellow, the NIRPS region is in cyan, and the CRIRES+ H-band and K-band are in purple and orange, respectively.
