    "abstract": "Positive operator valued measures (POVMs) are presented that allow an unknown\npure state of a spin-1 particle to be determined with optimal fidelity when 2\nto 5 copies of that state are available. Optimal POVMs are also presented for a\nspin-3/2 particle when 2 or 3 copies of the unknown state are available.\nAlthough these POVMs are optimal they are not always minimal, indicating that\nthere is room for improvement.",
