DoLP observed with VLT/SPHERE-ZIMPOL around the ATOMIUM sources when several filters have been observed. The white contours correspond to the 5σ level, and the dashed cyan circles correspond to distances of 10 and 20 R_⋆ from the star center. The red cross indicates the star position. The field of view is 1 arcsec x 1 arcsec for each source. North is up, and east is to the left. Note that the color scale has been adapted to each source to highlight the DoLP.
