Notes. The first letter of the ID indicates whether the spectropolarimetric sequence was taken with HARPS (H) or ESPaDOnS (E). For each sequence, the mid-exposure HJD, the exposure time, and the rotation phase, ϕrot, are indicated. The latter was determined with Prot = 2.95333 d and T0 = HJD 2455702.5. The provided S/N is that of the LSD Stokes I profile calculated with various line masks. In addition, the magnetic detection status is provided (DD = Definite Detection, MD = Marginal Detection, and ND = Non Detection) in case not all observations resulted in a DD for the given LSD line mask. (a) This observation was discarded because the last two sub-exposures in the sequence did not contain any signal due to bad weather.
