Planet scintillation as a probe for ground-layer turbulence

The MASS instrument measures scintillation indices (normal and differential) in 4 concentric apertures. From this data, the vertical distribution of turbulence (profile) is restored. With stellar source, the vertical resolution is ∼ 1/2 of the altitude, and usually 6 fixed layers from 0.5 to 16 km are fitted to restore the profile. Scintillations from a… CONTINUE READING
