High-accuracy differential image motion monitor measurements for the Thirty Meter Telescope site testing program

Not Accessible

Your library or personal account may give you access

Abstract

Differential image motion monitors (DIMMs) have become the industry standard for astronomical site characterization. The calibration of DIMMs is generally considered to be routine, but we show that particular care must be paid to this issue if high-accuracy measurements are to be achieved. In a side by side comparison of several DIMMs, we demonstrate that with proper care we can achieve an agreement between the seeing measurements of two DIMMS operating under the same conditions to better than ±0.02 arc sec.
