TMT - Contested Case Hearing Status - Hilo

[TomK]

Pahoated claimed:

"Mauna Kea has a mean seeing value of 0.88 so Chile and Canary island with 0.55 have much better seeing values. The air above Hawaii may be clearer but there is a lot more turbulence. The lower end of the India seeing value is comparable to Mauna Kea but they may have much less upper atmosphere turbulence on average."

Although there are small variations from site to site, Mauna Kea's median natural seeing is approximately 0.5 arcseconds.
