Planck 857 GHz dust map of the Chamaeleon region. The positions of the main dark clouds are denoted with white ellipses. The area studied in this work is encompassed by the orange lines. The known members of Cha I and Cha II star-forming regions are shown as filled orange circles and pink crosses, respectively (Luhman 2007; Luhman & Muench 2008; Mužić et al. 2011; Sacco et al. 2017; Spezzi et al. 2008). The open cyan circles denote the ϵ Cha members (Murphy et al. 2013), and red diamonds are kinematic candidates associated with the A0 group of LCC from Goldman et al. (2018).
