VizieR Online Data Catalog: EXPRES radial volocity for {tau} Ceti (Korolik+, 2023)
Abstract
The Extreme PREcision Spectrograph (EXPRES) at the 4.3m Lowell Discovery Telescope (LDT) run by Lowell Observatory was used to obtain 200 spectra of {tau}Ceti over the period of time from 2019 August to 2021 October. The data from EXPRES reach a median resolving power of R~137500 and an radial velocity precision of 30cm/s for main-sequence FGK stars with a target signal-to-noise ratio of ~250.
