Observatory Operations: Strategies, Processes, and Systems VIII.
Some of optical telescopes and millimeter- and submillimeter-wave telescopes are constructed on the top of the mountains which are higher than 4,000 meters above sea level, in order to prevent light from absorbing and diffusing and to avoid the influ
