    • Although orbital order and JT effect differ in their driving forces, an experimental distinction is extremely difficult or even impossible because both effects are strongly coupled to each other. In any material, orbital order will be accompanied by a lattice distortion which lowers the symmetry of the crystal field and enhances the splitting between the orbitals. In contrast, a collective JT effect gives rise to a spatial ordering of the occupation of the orbitals.

    • We mention that this result does practically not change, when we use different temperature intervals for the fit, e.g., 4 K < T < 200 K or 4 K < T < 400 K.

    • According to Refs. 9 and 17 the energy gaps decrease with increasing temperature above about 400 K, whereas Ref. 40 reports an increase of the energy gaps with increasing temperature starting already around 50 K.
