在托洛洛山美洲天文台（CTIO）进行为期四年的光学turbulence监测
Four years of optical turbulence monitoring at the Cerro Tololo Inter-American Observatory (CTIO)
摘要：
介绍了2004年至2008年底在Cerro Tololo上空测量的光学湍流条件及其季节性和夜间行为。进行了与30米望远镜现场测试的MASS-DIMM系统的比较，并确定了在偏北风下CTIO DIMM系统收集的数据中人为增加的视宁度分量。有证据表明，这种增加的湍流是由望远镜圆顶。尝试对此影响进行校正，并将其应用于CTIO DIMM数据。该比较活动的MASS数据允许对场地上方均匀湍流层的一般假设设置约束。
英文摘要：
The optical turbulence conditions as measured between 2004 until end of 2008 above Cerro Tololo, their seasonal as well as nocturnal behavior are presented. A comparison with the MASS-DIMM system of the Thirty Meter Telescope site testing was conducted and identifies an artificially increased seeing component in the data collected by the CTIO DIMM system under northerly winds. Evidence is shown that this increased turbulence is caused by the telescope dome. A correction for this effect is attempted and applied to the CTIO DIMM data. The MASS data of this comparison campaign allow to set constraints on the general assumption of uniform turbulent layers above a site.
