Position of intrinsic substructures (circles) with respect to the galaxy host color-coded with redshift. The detection is done in edge-on galaxies with bulges contributing less than 50% to the rest-frame NIR flux. We show on the x axis the distance to the center of the host galaxy and, on the y axis, the angle between the barycenter of the substructure and the major axis of the host galaxy. Crosses show the distribution of galaxy companions with properties comparable to clumps, selected at a distance below 3 arcsec from the galaxy, with a total flux in the rest-frame NIR below 15%, and within 1σ of the redshift of the main galaxy. Pink dotted lines represent isocontours of the vertical distance to the galaxy plane.
