Target stars with detected companions between 2'' and 4''. Each box is 12'' by 12''. KOI 266 also has a companion within 4'', but it is not pictured here because the companion is smeared due to field rotation. The color scaling is linear for K02939 and logarithmic for all other stars. Some stars also have more distant companions at separations between 4'' and 12''. We provide a list of companions within 10'' in Table 1.
