Hmm?..I would be doubtful of those figures (but happy to stand corrected
), that would make it the best observing site in the World. The only genuine study I have seen that compared Siding Spring with a site in SA, while site testing for the AAT, had the
averages around 1.3" I believe? (and seeing down at 0.5" a rare occurrence) with the site in SA slightly better slightly more often than Siding Spring?
