HARPS-N data on the transit night. Top: RVs extracted from the HARPS-N pipeline plotted against time. Middle: S/N for each exposure at three different orders, namely 45, 47, and 49. Bottom: airmass for each exposure plotted with the airmass of the Moon plotted as the dashed line. In each panel, the vertical solid and dotted lines denote nautical and astronomical twilight, respectively.
