VizieR Online Data Catalog: The TESS-Keck Survey. I. HD332231 Radial Velocities (Dalba+, 2020)

We began monitoring the Radial Velocity (RV) variation of HD332231 in 2019-October to measure the companion's mass and further characterize the system. The majority of the RV observations were acquired with the 2.4m Automated Planet Finder (APF) Telescope at Lick Observatory under the TESS-Keck Survey (TKS) and another program dedicated to single-transit follow-up (2019B-A006, PI:Dalba). We supplemented the APF data set with additional observations from the 10m Keck I telescope at the W.M. Keck Observatory.

Automated Planet Finder Telescope (APF)-Levy observed HD332231 using the W decker, which has a width of 1" in the spectral dimension and 3" in the spatial dimension. This slit provides a resolving power of R~114000 for a continuous spectrum between 3740 and 9700Å.

Keck-I is equipped with the High Resolution Echelle Spectrometer (HIRES). We acquired 13 high-resolution (R~60000) spectra of HD332231. We also acquired a high-S/N spectral template using Keck-HIRES that was used in the forward modeling procedure to determine the relative Radial Velocities (RVs) of HD332231.

Additional RV measurements were collected using the robotic 1m Hertzsprung Stellar Observations Network Group (SONG) telescope which is equipped with a high-resolution echelle spectrograph. Thirteen spectra of HD332231 were acquired (R~90000) covering the wavelength range 4400-6900Å. Each spectrum was obtained using an exposure time of 2700s resulting in an S/N of ~50.
