This opinion article will summarize most recent results obtained on this topic and will discuss the weaknesses and strengths of these techniques to open a constructive discussion with the scientific community.ELETTRONICOenArticle10.3389/fspas.2016.000172-s2.0-85063887514000453949300017http://arxiv.org/abs/1608.05536v1https://www.frontiersin.org/articles/10.3389/fspas.2016.00017/full2016FrASS...3...17BFIS/05 - ASTRONOMIA E ASTROFISICA
