Группа ученых из Университета Западной Австралии, используя 64-метровый радиотелескоп на частоте 4.46 ГГц, проводят исследования с целью обнаружения узких эмиссионных линий от отдельных выбранных звезд и шаровых скоплений Нулевые результаты поиска использовались для получения верхней оценки времени существования цивиллизации в коммуникативной фазе. Получено значение 100 миллионов лет.

... Robust Bandpass Removal Traditionally, the bandpass that is present in single­dish 21 cm spectra is re­ moved by observing in a ``signal­reference'' mode. ... Instead, a statistical estimate of the bandpass at the position and time that a particular spectrum---the target spectrum---was acquired is made from a set of earlier and later spectra observed by the same beam---these are the reference spectra. ... I b,p,c is a 1024­ channel flux density spectrum. ... References Barnes, D. G. 1998, this...
