Stokes-I (left) and Stokes-V (right) images of the area surrounding WX UMa. The images are formed from the entire 8 hour observation duration and entire 44 MHz bandwidth (120–167 MHz). The cross-hairs and circles show the proper-motion corrected position of WX UMa (GJ412 B) and GJ412 A, respectively, using the astrometric data from Gaia DR2 (Gaia Collaboration 2018). The flux densities of WX UMa and uncertainties are collated in Table 1.
