Notes. Stellar parameters are from Maldonado et al. (2020). Along with the number of observations Nobs, the numbers in parentheses indicates the numbers of activity-related outliers, if any, identified in each time series as discussed in Sect. 3.3. The listed rotation periods are from Suárez Mascareño et al. (2018); the values derived activity-rotation relationships are marked with a(*) (see Sect. 2). The last column indicates the references for the published systems.
