Upper panel: difference between our FPI wavelength solution and the DRS wavelength solution (solid lines) with an rms of 22 m/s. Difference between FPI wavelengths obtained from the model d(k) and the wavelengths assigned to the FPI from DRS wavelength solution (points). Lower panel: same as above, but using the LFC wavelength solution of Molaro et al. (2013). Orders 116128 are shown here.
