D/H ratios of water and organic molecules measured in different comets compared to values from the Protosolar Nebula (purple line, Geiss & Gloeckler 2003), the Earth (green line, Wilson 1999), carbonaceous chondrites (CC), ordinary chondrites (ОС), interplanetary dust particles (IDP) and ultracarbonaceous Antarctic micrometeorites (UCCAM). D/H in HDO is equal to 2 · D2O/HDO. Full references are given in Table B.1.
