VizieR Online Data Catalog: CoRoT-30b and CoRoT-31b radial velocity curves (Border+, 2020)

Radial velocity measurements of CoRoT-30 and CoRoT-31 were obtained with the HARPS spectrograph. HARPS is a cross-dispersed echelle spectrograph fiber-fed from the Cassegrain focus of the 3.6m telescope at La Silla Observatory, Chile. We obtained 18 and 17 spectra of CoRoT-30 and CoRoT-31, respectively, with exposure times ranging between 3300s and 3600s. We used the high-accuracy mode (HAM), with spectral resolution R~115000. For the observation of these faint targets, one of the two available fibers was set on the sky in order to monitor the moonlight and to obtain the best-fit sky background subtraction. The S/N per pixel at 550 nm ranges from 2.2 to 6.8 for CoRoT-30 and from 3.2 to 6.8 for CoRoT-31, which translates into photon noise uncertainties of about 30-40m/s.
