Analysis of HARPS Astro-Comb data

"The HARPS astro-comb was repaired in October 2016, and it is under unsupervised operations since. In this poster we show the analysis of the comb data, in particular the presence of a wavelength dependent background \ncontinuum. We are able to characterise this background with respect to wavelength and time. We show that its proper evaluation is essential to optimize the performances of the system.
