(a) Data collected for large θ range (from 0° to 90°). The red solid line shows the best fit to Eq. (4). (b) Data collected within a small θ range (from 70° to 90°). The blue solid line represents the best fit to Eq. (4) with the value of HK fixed. The blue dotted lines in (b) are the best fits for the cases with δHK =±10 mT.
