Double eclipsing binaries in HR-diagrams. Left: HR-diagram of all 1 210 001 binary objects in the sample. The double eclipsing binary candidates and test objects, separately plotted as dots, are scattered throughout the diagram and do not seem to have any preferred location. Using the sun as a reference with M_G = 5 and G_BP − G_RP = 1, a larger number of objects seem to be similar to the sun. Right: an HR-diagram of all stars in the Gaia DR3 archive within 200 pc of the Sun. The candidates and test objects are systematically above the single stars in this diagram and are mostly sun-like stars. The arrow with a length of 1.505 magnitude indicates where one star in the quadruple system would lie, assuming all stars in the system are equally bright.
