Radial-Velocity Time Series of Seismic K Dwarfs from ESPRESSO Observations

This dataset compiles raw radial-velocity time series obtained as part of an asteroseismic survey of bright southern and equatorial K dwarfs with ESPRESSO@VLT (Campante et al. 2024). The spectra were reduced with version 3.0.0 or later of the ESPRESSO Data Reduction Software (DRS; Pepe et al. 2021), and radial velocities were subsequently derived via cross-correlation. The current release includes time series for the following targets (refer to file headers for column descriptions): ϵ Indi - ESO program 0109.D-0619(A), PI: Campante; see Campante et al. (2024) HD 40307 - ESO program 0102.D-0346(A), PI: Bouchy; see Campante et al. (2024) HD 131977 - ESO program 0113.D-0255(B), PI: Campante; see Campante et al. (in prep.) HD 191408 - ESO program 0113.D-0255(A), PI: Campante; see Campante et al. (in prep.)
