χ¹ Ori in a) C-band with contour levels [0.2, 0.4, 0.6, 0.8] · 223 μJy; b) Ku-band with [0.2, 0.4, 0.6, 0.8] · 106.6 μJy; and c) for ALMA at 100 GHz with [0.2, 0.4, 0.6, 0.8] · 108 μJy. The black dot represents the coordinates calculated from the Gaussian fit. The red cross marks the position of the companion χ¹ Ori B and the black cross the corrected coordinates of the main target χ¹ Ori.
