tokens: Acknowledgements This research has made use of the high performance computing cluster at the Abdus Salam Centre for Physics, Pakistan and the supercomputer Leftraru, Chile. The first author (R.R.) gratefully acknowledges support from the Department of Astronomy, University of Concepcion, Chile. The first author R.R. and third author D.R.G.S. are thankful for funding through the “Concurso Proyectos Internacionales de Investigación, Convocatoria 2015” (project code PII20150171). D.R.G.S. is further thankful for funding via Fondecyt regular (project code 1161247) and via the Chilean BASAL Centro de Excelencia en Astrofísica yTecnologías Afines (CATA) grant PFB-06/2007, and ALMA-Conicyt project (proyecto code 31160001). The second author (S.V.) developed the computer code that has been used in this work on the HPC system Thinking at KU Leuven, which is part of the infrastructure of the FSC (Flemish Supercomputing Center). We thank the KU leuven support team for helping with the use of this system. The second author also gratefully acknowledges the support of Prof. Dr. Stefaan Poedts and Prof. Dr. Rony Keppens for having provided both access and funding, which made the use of the KU Leuven HPC infrastructure possible.
