Final probability distributions of the signals of DH Tau B in I_Q, I_U , Q, and U (top row), and in normalized Stokes q and u, degree of linear polarization, and angle of linear polarization (bottom row) from the 2019-10-24 data set of DH Tau, using an aperture radius of 8 pixels. The median values of the distributions, as well as the uncertainties computed from the two-sided 68.27% equal-tailed interval around the median, are shown above the graphs. The S/N, i.e., the median value divided by the largest uncertainty, is shown within parentheses. The 68.27% intervals are also indicated by the light-blue and light-red shaded areas.
