Diagnosing spatial-coherence outer scale, seeing, and dome-induced turbulence from simultaneous multi-wavelength imaging of point-like sources
Atmospheric turbulence causes refractive-index fluctuations that distort the wavefront of light from astronomi cal sources. As starlight propagates through multiple turbulent layers, the cumulative effect sets the achievable image quality (IQ) of observations obtained with ground-based telescopes. Global parameters suc...
