Simple spectroscopic programme on two young brown dwarf candidates Cha Halfa 4 (part I, already completed) and Cha Halfa 8 (part II, for P69) with the aim of confirming the planetary mass of the companion and derive the orbital solution. Part II: program consists of 4 identical OBs, to be executed on 4 different (randomly distributed) nights. Every OB contains 2 science exposures of 2200s each, each followed by a ThAr.
