The probability density that the angular\nseparation between the points have a given value is obtained. The knowledge of\nthis function is important for some methods for determining the shape of the\nuniverse.\n  -----\n  Kaloto de 2-D sfera estas studata, pli malgranda ol duonsfero. Du punktoj\nestas hazarde elektataj en la kaloto. La probabla denso de angula distanco\ninter la punktoj estas havita. Scio de tiu funkcio estas grava por kelkaj\nmetodoj por specifi la formo de l\u0027universo.",
