Chajnantor frequently exhibits significant transmission in atmospheric windows at frequencies above 1 THz. Here we outline the design and characteristics of the instrument, discuss data processing ...

This region includes a number of so-called water windows: wavelengths of light that can propagate through the Earth’s atmosphere without being absorbed by water molecules. It is also highly ...

450-461 (12 pages) ABSTRACT Many adaptive optics systems operate by measuring the distortion of the wave front in one wavelength range and performing ... We demonstrate the importance of atmospheric ...
