VizieR Online Data Catalog: Radial velocities of 8 stars with giant planets (Hebrard+, 2016)
Résumé
We observed the eight stars with SOPHIE at the OHP 1.93m telescope. SOPHIE is a cross-dispersed, environmentally stabilized echelle spectrograph dedicated to high-precision radial velocity measurements. Observations were secured in fast-reading mode of the detector and in high-resolution mode of the spectrograph, allowing a resolution power of λ/Δλ=75000 to be reached. Depending on the star, the spectra were obtained over time spans of two to eight years. Their typical exposure times are a few minutes to reach a signal-to-noise ratio per pixel at 550nm of around 50. The final dataset presented here represents nearly 600 exposures for a total integration time exceeding 60 hours on the sky. (2 data files).
