From this result, it can be stated that for 𝑇 2 (0) ≠ 𝑇 0 (0), the solution by Peigné et al. (Eq. ( ) from ) is incorrect for 𝑇 2 and, therefore, does not have a general character. Also note that the results in Fig. are consistent with Eq. (B4). The solution proposed by Peigné et al. is also presented in an identical form in Peigné's doctoral thesis . These authors were unable to find any erratum or corrigendum regarding this solution.
