Notes. The columns are the following: 1) date of the observation, 2) universal time of the observation, 3) heliocentric Julian date, 4) rotational cycle as computed from Eq. A.1, 5) signal-to-noise ratio per resolution element per polarimetric sequence at 650 nm, 6) RMS noise level of Stokes V signal in units of unpolarised continuum, 7) longitudinal magnetic field, 8) S-index, 9) log R′HK index, 10) Hα index, and 11) Ca II infrared triplet index. The first observation marked with * was not used due to low signal-to-noise ratio.
