Details of the HRV and the LRV sketched in Fig. 2. The features discussed in the text are labeled with capital letters. The yellow dotted lines in panel (c) indicate the main alignments of the elongated branches that cross part of the LRV. The figure was created by the Visit 3.1.2 (https://wci.llnl.gov/simulation/computer-codes/visit) open-source software produced by the Lawrence Livermore National Laboratory (USA) and postprocessed using the Corel Draw 17 commercial software (https://www.coreldraw.com/it/product/coreldraw/).
