Notes. Column 1 indicates the number of the polarimetric sequence. Columns 2 and 3 show the date and time of the middle of observations, while Col. 4 gives the Heliocentric Julian Date (HJD) at the middle of observations. Column 5 gives the exposure time in seconds for each sequence, and Col. 6 the rotational phase using Prot = 3.638833 d and HJD0 = 2 447 383.89.
