Measuring and characterizing the line profile of HARPS with a laser frequency comb
Aims: We study the 2D spectral line profile of the High Accuracy Radial Velocity Planet Searcher (HARPS), measuring its variation with position across the detector and with changing line intensity. The characterization of the line profile and its variations are important for achieving the precision of the wavelength scales of 10 -10 or 3.0 cm s -1
