  (5)~Sz 41~A: probable SB (Reipurth et~al. \cite{Reipurth_etal2002}) with period of about 125~days (best candidate out of five~radial-velocity variables). 
  (6)~CV~Cha: possibly SB, variable radial-velocity (Reipurth et~al. \cite{Reipurth_etal2002}).  
  (7)~Haro 1-14c: 591-days SB1 (Reipurth et~al. \cite{Reipurth_etal2002}), converted to SB2 by Simon \& Prato \cite{Simon_Prato_2004}.
  (8)~ROXs 43~A: 89-days SB1 (Mathieu et~al. \cite{Mathieu_etal1989}).
