Notes. Columns are: date of observation (UTC), total observation duration (T), Min and Max values of airmass during the data acquisition, number of observations (N), Min and Max RV errorbars (σRV), duty cycle (DC), standard deviation of the detrended RV time series (σTOT), and median value of the log R′HK activity indicator.
