Notes. The recovery rates are defined as in Table 3 for an error of <15°. The recovery rates shown in this table correspond to the mean values found for regions with a total linear polarized intensity normalized to the peak value (PInorm = PI/PIpeak) higher than 10−2, 10−3, and 10−4, respectively. These values correspond to the first three contours of Fig. A.1. As in Table 3, the corresponding standard deviations are given in a smaller font.
