亚毫米波天文的观测条件

Observing Conditions for Submillimeter Astronomy

Simon J. E. Radford

摘要:

然而,优良的观测条件对于实现望远镜的科学目标至关重要。亚毫米波天文学只有在少数特别干燥的地方才有可能,特别是莫纳克亚山、南极高原和智利北部圣佩德罗德阿塔卡马以东安第斯山脉的查南托地区。对225 GHz和350 μm大气透明度的长期测量表明,这三个地点都有相当长的观测条件。Chajnantor高原和南极的条件往往比莫纳克亚山好。冬季和夜间的条件更好。在Cerro Chajnantor山顶附近,条件比Chajnantor高原好。

英文摘要:

Consistently superb observing conditions are crucial for achieving the scientific objectives of a telescope. Submillimeter astronomy is possible only at a few exceptionally dry sites, notably Mauna Kea, the Antarctic plateau, and the Chajnantor region in the high Andes east of San Pedro de Atacama in northern Chile. Long term measurements of 225 GHz and 350 μm atmospheric transparency demonstrate all three locations enjoy significant periods of excellent observing conditions. Conditions on the Chajnantor plateau and at the South Pole are better more often than on Mauna Kea. Conditions are better during winter and at night. Near the summit of Cerro Chajnantor, conditions are better than on the Chajnantor plateau.
