VizieR Online Data Catalog: HARPS-N radial velocities of WASP-47 (Vanderburg+, 2017)
Abstract
We observed WASP-47 with the HARPS-N spectrograph on the 3.58 m Telescopio Nazionale Galileo (TNG) on the island of La Palma, Spain (Cosentino et al. 2012SPIE.8446E..1VC). HARPS-N is a stabilized high resolution (λ/Δλ=115000) optical spectrograph designed specifically to make precise radial velocity measurements. We began observing WASP-47 on 2015 July 23, shortly after K2 data revealed the presence of two small transiting planets (WASP-47 e and WASP-47 d) in addition to the previously known hot Jupiter (WASP-47 b). We obtained 78 observations of WASP-47 with integration times of 30 minutes. We measured radial velocities for each exposure by cross-correlating the HARPS-N spectra with a weighted binary mask (Baranne et al. 1996A&AS..119..373B; Pepe et al. 2002, J/A+A/388/632).
