Summary

Description
English: In the late 1940s and early 1950s, CSIRO scientists used a technique based on Lloyd's mirror to make accurate measurements of the position of various galactic radio sources from coastal sites in New Zealand and Australia. The technique was to observe the sources combining direct and reflected rays from high cliffs overlooking the sea. After correcting for atmospheric refraction, these observations allowed the paths of the sources above the horizon to be plotted, and their celestial coordinates to be determined.
Русский: В конце 1940-х и начале 1950-х годов ученые из CSIRO использовали метод, основанную на идее зеркала Ллойда, для точных угловых измерений положения различных галактических радиоисточников. с прибрежных участков. Методика заключалась в наблюдении интерференции прямых и отраженных от поверхности моря радиолучей. Приемник располагался на высоких прибрежных скалах Новой Зеландии и Австралии. Эти наблюдения после поправки на атмосферную рефракцию и обработки позволили построить траектории движения источников над горизонтом и точно определить их небесные координаты.
