Image stamps showing the combined maps of Sedna (upper panels) and 2010 EK₁₃₉ (lower panels) in the 70   μm (blue), 100   μm (green), and 160   μm (red) channels. Each stamp covers an area of 56′′ × 56′′, while the tick marks on the axes show the relative positions in pixels. The effective beam size (i.e. the circle with a diameter corresponding to the full width at half magnitude) is also displayed in the lower-left corners of the stamps.
