Notes. The columns contain the date, the corresponding Heliocentric Julian Date (HJD), the start time of the observations in UT, the exposure times, and the Stokes I peak signal-to-noise ratio (S/N). The rotational phase (Φ) listed in the last column is calculated using the rotation period derived in this work (Prot = 7.0 d).

(a)

The listed values correspond to two spectro-polarimetric exposures merged in a single observation due to bad weather conditions.
