Notes. Column 1 indicates the number of the polarimetric sequence. Columns 2 and 3 provide the rotational phase Φ assuming HJD0 = 2   455   000 and Prot = 0.85137 d or 5.73 d, respectively. The last 10 columns give the longitudinal magnetic field value in Gauss and their error bars, calculated using a LSD submask that contains all but He, only He, O, or C lines, or only the Hα line respectively.
