Corrigendum to "On the edge-length ratio of outerplanar graphs" [Theoret. Comput. Sci. 770 (2019) 88-94].

Due to an editorial oversight, a flaw in the proof (not the result) of Lemma 5 remained in the TCS published version of the following paper “On the edge-length ratio of outerplanar graphs”, published in Theoretical Computer Science, vol. 770, pp. 88–94, 2019. Please refer to the electronic version on HAL (https://hal.inria.fr/hal-01886947) for the correct version.
