We pointed out a few cases where a further observational effort would largely improve the reliability of the orbital solutions.STAMPAenArticle10.1140/epjp/i2017-11621-72-s2.0-85027101105000407293000003https://epjplus.epj.org/articles/epjplus/abs/2017/08/13360_2017_Article_1784/13360_2017_Article_1784.html2017EPJP..132..349BFIS/05 - ASTRONOMIA E ASTROFISICAERC sectors::Physical Sciences and Engineering
